1. What This Concept Is About
1.1 Their Position in the Twelve Sense Bases / Six Sense Objects
Buddhism divides the complete structure of existence into the twelve sense bases (十二處, dvādaśāyatana): six sense faculties (六根, ṣaḍ-indriya) plus six sense objects (六境, ṣaḍ-viṣaya). The six sense objects are: form (色, rūpa), sound (聲, śabda), odor (香, gandha), taste (味, rasa), tangible (觸, spraṣṭavya), and mental objects (法, dharma).
- What the eye sees — form (rūpa in the narrow sense: shapes, colors, etc.) - What the ear encounters — sound (聲, śabda) - What the nose encounters — odor (香, gandha) - What the tongue encounters — taste (味, rasa) - What the body encounters — tangible (觸, spraṣṭavya) - What the mind encounters — mental objects (法, dharma)
The four characters "聲香味觸" occupy four seats among the twelve sense bases — four kinds of objects that, without depending on the eye, are nonetheless material in nature. Together with the forms seen by the eye, they constitute the "five sense objects" (五塵, pañca-viṣaya); the sixth, the "dharma-object" (法塵), is the general, abstract object seized upon by the mind-consciousness (意識, mano-vijñāna).
Thus "聲香味觸" does not mean four physiological sensations, but rather objects that stand outside the mind, exist objectively, and are available for the ear, nose, tongue, and body faculties to take up — they are material existences with location, density, and arising-and-ceasing (in the Abhidharma (阿毗達磨, abhidharma), sound, odor, taste, and tangible are classed as four subdivisions of "material phenomena" (色法, rūpa-dharma)). They are the objects that need no seeing with the eye: the ear already hears, the nose already smells, the tongue already tastes, the body already touches.
"Sound" (聲) is the sound-dust (聲塵) that the ear faculty (耳根) takes as its object; "odor" (香) is the odor-dust (香塵) that the nose faculty takes; "taste" (味) is the taste-dust (味塵) that the tongue faculty takes; "tangible" (觸) is the tangible-dust (觸塵) that the body faculty takes. Together with the faculties and consciousnesses, they are the basic particles through which this world unfolds sensorially.
1.2 Sound (聲): The Object of the Ear Faculty
The standard definition of "sound" in the scriptures: the characteristic taken by the ear faculty and discerned by ear-consciousness (耳識, śrotra-vijñāna). It can be divided into several types:
- Agreeable sound (可意聲) — pleasant, beloved sound. A lover's soft voice, music, a sentence that warms the heart. - Disagreeable sound (不可意聲) — noise, angry words, startling sounds. - Neutral sound (俱相違聲) — background sound that is neither liked nor disliked.
The Yogācāra (唯識, vijñapti-mātra) system particularly reminds us: sound is classed as a special subdivision of material phenomena (色法). On the surface, sound is "formless and massless," but in the Abhidharma definition, sound is a form-dust (色塵) that has physical resistance (can obstruct other things), has location (this sound here differs from that sound there), and arises-and-ceases (perishes in an instant). In a plain scientific understanding — sound is a mechanical wave, a vibration of density in particles, an event, not a thing. In the Buddhist system: sound is not a stably existing "thing" but a "event-phenomenon" (事相) arising from causes and conditions.
In the *Saṃyuktāgama* (《雜阿含經》), in its "Six Sense Bases" section (六入處相應), the Buddha teaches disciples to observe things as they really are: sound is impermanent (無常, anitya), is suffering (苦, duḥkha), is a dharmic process of change (變易之法). This observation itself is the entry point into the practice of the twelve sense bases.
Curbing the clinging of the ear-gate (耳門) is a topic the Buddha repeatedly touches in the scriptures. A well-known formulation: "dwell with vigilance at the ear-gate" (於耳門不放逸住). Meaning: when the ear faculty meets sound and desire-and-grief (欲貪憂戚) arise toward sound, that is the domain where Māra operates; correctly observing the ear-gate, not clinging or grieving toward sound, is the beginning of good liberation.
1.3 Odor (香): The Object of the Nose Faculty
Odor is the object taken by the nose faculty and discerned by nose-consciousness (鼻識, ghrāṇa-vijñāna) — not limited to pleasant flowers, fruits, sandalwood, aloes, and herbs; it includes three types:
- Good odor (好香, sugandha) — flowers, spices, incense. - Bad odor (惡香, durgandha) — rot, smoke, filth. - Neutral odor (平等香) — smells with no marked like or dislike.
Odor is likewise classed as material phenomena (色法) in Yogācāra. It has a material property often overlooked: what the nose takes in is drifting particles of dust (微塵) — material carried by wind, heat, and other conditions into the nostrils, giving rise to the odor-dust before the nose. In scientific terms, odor is molecules — matter that can enter olfactory receptors.
The special quality of odor is often pointed out in the scriptures with the word "odor-craving" (香貪) — the nose's attachment to odor is one branch of sensual craving (欲貪, kāma-rāga). In the contemporary world this branch is especially activated: perfume has become part of identity, home fragrance has become the olfactory signature of a space, coffee aroma serves as the opening ritual of a day. To understand the single character "香" is to understand how much desire-bound attachment has been industrialized into the nose.
1.4 Taste (味): The Object of the Tongue Faculty
Taste is the characteristic taken by the tongue faculty and discerned by tongue-consciousness (舌識, jihvā-vijñāna). The scriptures give different systems of varying detail; one common one is the "six tastes" (六味): sweet, sour, salty, bitter, pungent, bland.
A key point: the establishment of taste requires direct contact between the tongue faculty and the material object (food or drink). That is, taste is not something that drifts freely; it must be "held in the mouth," "tasted with the tongue," for taste-sensation to arise. This distinguishes it from odor (freely drifting particles) and from tangible (which need not enter the mouth).
A distinction that is often overlooked:
味是滋味（甘酸咸苦等），与触中的「涩滑冷暖软硬」并不相同。 *"Taste is the flavor (sweet, sour, salty, bitter, etc.), and is not the same as the 'rough-smooth, cold-warm, soft-hard' in the tangible."*
When the tongue tastes a strawberry: - The "sweetness" is taste (味); - The "juiciness of the flesh," the "fine grain of the skin," "the temperature in the mouth" are tangible (觸). Taste and tangible occur simultaneously at the tongue, but what is discerned differs.
The scriptures have a reminder: the tip of the tongue is more attuned to the Dharma: 「飲食為已，不為嬉戲、驕慢、莊嚴、裝飾」 (*"eat for the sake of sustaining, not for play, pride, adornment, or decoration"*) — a single sentence that names the most hidden forms of the tongue's attachment to taste (showing off, comparison, emotional comfort).
1.5 Tangible (觸): The Object of the Body Faculty
Tangible is the object taken by the body faculty and discerned by body-consciousness (身識, kāya-vijñāna). The scriptures link it to the combination of the "four great elements" (四大, mahābhūta) (earth, water, fire, wind):
- The most basic tangibles are four pairs, eight kinds: rough-smooth (earth element), heavy-light (water element), cold-warm (fire element), hard-soft (wind element); - Or adding hunger, thirst, satiety as internal bodily tangibles; - The scriptures also divide tangibles into three kinds: agreeable tangible (comfort, warmth, softness, suitability), disagreeable tangible (cold, rough, pressure, discomfort), neutral tangible.
Tangible differs from the everyday term "touch sensation." In the twelve sense bases, tangible is the condition-based object where the body faculty meets external matter — it requires the body faculty and the touched object to contact each other, plus body-consciousness (touch-consciousness) to constitute "tangible." An object seen by the eye but not contacted by the body does not give rise to "tangible" — it is only form-dust.
Tangible is the sense object closest to the person and the most easily overlooked. It wraps the body: the warmth of a blanket, the support of a chair, the hardness of the ground, the temperature of air, the speed of the wind, the texture of clothing. It is always there. Tangible is the deepest domain of contemporary commerce — from clothing to bedding, from skin care to massage devices, from towels to sofas, from hot springs to fitness equipment, "touch" is sliced so finely that you come to believe "consumption is the way of touching the world."
1.6 The Four Things They Share
Whether sound, odor, taste, or tangible, each simultaneously possesses these properties:
First, they are all material — belonging to the scope of "material phenomena" (色法). In Yogācāra, sound, odor, taste, and tangible, together with form (色) and the five faculties (eye, ear, nose, tongue, body), all belong to material phenomena. They all have: - Physical resistance (有質礙): can obstruct other things, occupy space; - Location (有方位): this thing here differs from that thing there; - Instantaneous arising-and-ceasing (剎那生滅): the sound, odor, taste, or tangible of this moment is not identical with that of the next.
This is why, when we hear "the same song," we feel it continues — but in truth it is countless instants of sound-dust arising and ceasing — the five sense objects have no enduring self at all.
Second, they all arise through the combination of causes and conditions (因緣和合). Sound relies on a vibrating source, a medium, and the ear faculty; odor relies on molecules, air, and the nose faculty; taste relies on food and tongue-faculty contact; tangible relies on external matter meeting the body faculty. When conditions are complete, they arise; when conditions disperse, they cease. No single thing can exist apart from causes and conditions.
Third, they are all neutral existences; defilement and purity lie in the mind. Sound, odor, taste, and tangible are neither bad nor good. Their existence itself is a "morally neutral" (無記, avyākṛta) matter. Defilement and purity, good and evil, occur at the moment the mind meets the faculty, consciousness, and object. A song can calm you or agitate you — it is not the difference of the song, but the difference of you.
Fourth, they correspond to the most direct objects of sensual craving's attachment. The secular world has the saying "five desires" (五欲, pañca-kāma) — form, sound, odor, taste, tangible — not including mental objects (法). This is because the first five are the objects in the desire realm (欲界) most apt to stir the ordinary mind.
- Form (色) — the eye's craving; - Sound (聲) — the ear's craving; - Odor (香) — the nose's craving; - Taste (味) — the tongue's craving; - Tangible (觸) — the body's craving.
Each of the five desires corresponds to a sensory object that instinctively wants, and gives rise to affliction when not obtained. Knowing that they are "entry points" (入處, āyatana), the remedy begins here.
1.7 A Famous Line Known to Everyone
In the popular edition of the *Diamond Sutra* (《金剛經》, Vajracchedikā Prajñāpāramitā Sūtra), there is a passage nearly everyone can recite — the source of the famous phrase "give rise to a mind without abiding anywhere" (應無所住而生其心). The original has at least several translations; one common formulation is:
「是故，須菩提，菩薩應如是生清淨心：不應住色生心，不應住聲香味觸法生心，應無所住而生其心。」 *"Therefore, Subhūti, the bodhisattva should give rise to a pure mind thus: not abiding in form, give rise to the mind; not abiding in sound, odor, taste, tangible, or mental objects, give rise to the mind; give rise to a mind that abides nowhere."*
"住" (to abide), in context, means "staying, holding onto, craving." "生心" (give rise to mind) means letting the mind cling to and grasp appearances at that point. The whole sentence means: at every object — seeing form, hearing sound, smelling odor, tasting flavor, feeling tangible, thinking of mental objects — one should not let the mind stay, cling, or attach; one should give rise to a mind that "abides nowhere."
The six characters "色聲香味觸法" are precisely the collective name of the six sense objects. "聲香味觸" thus appears here alongside "色" and "法" as the full set of objects toward which "abiding nowhere" applies.
This is the position where "聲香味觸" is pointed to in a scripture known in every household — it is one of the four pillars of "abiding nowhere" in that famous line.
2. Walking Through Daily Life
Below, we walk through a contemporary person's day, passing through these four sense objects one by one. We are not seeking a practice that despises the senses; we are looking at: at what moment does the mind get swept away by which object? Clear observation of sound, odor, taste, and tangible begins here.
2.1 Sound — The World of the Ear
In the morning the alarm rings — sound. Going out, in the subway — broadcasts, voices, rail friction, someone's phone video playing aloud — sound. Entering the office, putting in earbuds, background music or white noise all morning — sound. The noisy cafeteria at lunch, the hubbub — sound. Driving home from work — navigation voice, the engine's hum you can't turn off in traffic, the radio host bubbling away — sound. At night before sleep, earbuds with a podcast, "scrolling videos" and listening to short clips — sound. A partner's breathing, the clock's second hand, a stray cat in the distance, footsteps upstairs — sound.
You will notice: in contemporary life, the ear almost never experiences silence.
How the classics map it:
- Agreeable sound: the song you loop ten times, a partner's soft "darling," a child calling "Mama," the voice of a favorite podcast host — ear-craving (耳貪). - Disagreeable sound: a neighbor's loudspeaker, subway short-videos, a renovation drill, a partner's tone suddenly turning cold — ear-aversion (耳嗔), grief. - Neutral sound: subway operation, refrigerator hum, fan rotation — background sound, often unnoticed, but it drains your awareness.
Common mapping errors:
- Treating "listening to music I like" as "relaxation." Music can be relaxation, but when it becomes an escape (avoiding emptiness and noise), it has already turned from agreeable sound into a vehicle of sensual craving. - Treating "musical taste" as spiritual refinement. Aesthetic preference is not a crime, but clinging to "I understand it better than you," "I only listen to such-and-such school" — that is self-conceit (我慢, asmi-māna) on the ear faculty, still "abiding." - Absolutizing "background sound helps focus." A quality can be an auxiliary condition in the work moment, but being hung entirely on background sound and afraid to enter silence is the ear faculty's dodging of stillness.
A line from the classics worth placing at the ear-gate every day: observe the arising and ceasing of sound-characteristics; do not let the ear faculty slide along them into craving and grief. The classics say "dwell with vigilance at the ear-gate" — not "do not listen," but "listen without being swept away."
2.2 Odor — The World of the Nose
Going out, just entering the elevator, corridor, office lobby — today's coffee, wood-scented air freshener, cigarette smoke. Entering the subway — carriage smell, sweat, tissue fragrance, breakfast bun smell. At the office — the coffee machine brews another pot, traces of makeup fragrance lingering in the meeting room. Lunch — the aroma of food from the cafeteria, barbecue smoke from street restaurants. Afternoon — a colleague orders milk tea — caramel smell; another colleague sprays perfume — a waft of fragrance in the air. Evening, going home — the smell of a partner, or the clean scent of laundry detergent left on the sheets.
You will notice: the sense of smell is a deep battleground of contemporary consumerism. Perfumers know: perfume is not just a product; it is "the smell of identity." From the myriad industrial essences to "unscented premium" (unscented is also an expression of scent), the battle for the nose rages day and night.
How the classics map it:
- Good odor: your signature scent, fine coffee, the hint of hair fragrance when first meeting a partner. - Bad odor: subway sweat, cigarette smoke, a stranger's heavy perfume, a roadside trash can. - Neutral odor: the insignificant "neutral smell" in the air — often you are not aware of it, but it silently underwrites your state.
A few mapping errors particularly easy to step into in the contemporary world:
- Marketing language disguised as "nose preference." Merchants use "vanilla scent," "lemongrass scent" to package "health," "naturalness," and make you buy on impulse. You are not living in "this scent makes home warm"; you are living in "marketing is guiding you." Dwelling in that scent without knowing it — this is the modern form of nose-craving (鼻貪). - The entanglement of memory and scent (modern psychology calls it the "Proust effect" — smell evokes memory). Buddhism teaches that the odor-dust is part of material phenomena, and reminds us further: odor is an object of the external sense bases, not "my" private memory bank. Letting oneself be repeatedly carried back to the past by a scent is not "I am so sensitive"; it is abiding. - Mistaking "olfactory purity" for "no smell." A pure, scent-free space is also an expression of the odor-domain, not its elimination.
2.3 Taste — The World of the Tongue
Breakfast: rice porridge, coffee, bread — the temperature, sweetness, and layer of ingredients in this mouthful. Lunch: a rice bowl, a light salad (or a heavy-spice hotpot). Afternoon: milk tea, coffee, snacks. Dinner: home-cooked or delivery — the tongue's detailed feedback on oil, salt, and sugar. Before sleep: dessert, late-night snack, a small drink.
You will notice: the contemporary tongue is more stimulated than in any previous era. A hundred years ago, taste stimulation was seasonal and regional; today the tongue is fed year-round by globalized flavors — sugar, salt, oil, spice, MSG, yeast extract, compound seasonings all at once. The tongue's taste threshold rises year by year. This is the "entropy of taste" (味的熵) — the randomness of stimulation grows ever greater and stronger.
How the classics map it:
- Agreeable taste (可意味): sweet fruit, fine tea, clean liquor. - Disagreeable taste (不可意味): bitter medicine, spoiled food, overly spicy food. - Neutral taste (俱相違味): plain water, bland rice, non-stimulating flavors.
The most easily overlooked mappings:
- "Using eating to regulate emotion." Not happy today — eat something sweet; tired today — eat something spicy. The tongue's role as a mechanical arm of emotional regulation is itself the contemporary form of taste-clinging. - Taste bound to prestige and profit. "When I treat, we must go to the most prestigious place"; "I must check in at that trendy spot" — the tongue is bound to self-display. - The self-discipline of "no sugar today." It is a healthy choice, but if it has become a new form of self-aggrandizement — "I am more disciplined than you" — that is still abiding, just with different content.
A relevant reminder from the classics: eat for the sake of sustaining, not for play, not for pride. This is a teaching that directly addresses contemporary taste-clinging.
2.4 Tangible — The World of the Body
Waking at dawn — the warmth of the blanket, the coolness as fingers reach out from under the covers. The temperature and pressure of water on the body during a shower. Going out — the cold and damp of wind on the face. Subway — the hardness of the seat, the cold of the handrail. Office — the softness/hardness of the chair, keyboard feedback, desk temperature. Lunch — the chair's support as you sit down, the rough-smooth of the wiped table surface. Afternoon — handshakes, high-fives, hugs, massage, stiff shoulders and neck. Night — the alternation of hot and cold in the bath, the temperature of slippers, contact with family. Before sleep — the softness of the sheets, the warmth of the covers.
Tangible is the sense object that the contemporary person can feel without focusing attention — it directly wraps the body and is always present. But it is also the most easily ignored — because your attention is usually taken by the eyes, ears, and discursive thought.
How the classics map it:
- Agreeable tangible: cotton and linen softness, warm covers, relaxing massage. - Disagreeable tangible: cold, heavy pressure, soreness, itch, heat, too tight. - Neutral tangible: ordinary sitting, walking, the unremarkable touch of gravity evenly distributed.
A few special points worth naming about contemporary tangible:
1. Tangible is the deepest sense-domain of commerce — from clothing to bedding, from skin care to massage devices, from towels to sofas, from hot springs to gyms. "Feel" is sliced with extreme fineness, making you believe consumption is the way of touching the world. 2. Tangible is the most neglected sense-domain — far lower in attention than sound, color, and taste, yet tangible is with you every day.
The two most common mapping errors:
- Treating massage as the whole of "relaxation." Massage is certainly comfortable, but letting it replace awareness of the body — that is precisely the contemporary form of "abiding in tangible" (住於觸). - Treating avoidance of touch (not going out, keeping distance, remote video) as practice. Not touching does not mean letting go; it may be suppression, it may be indifference, it may be amnesia of bodily sensation — not liberation.
2.5 Coordinated Stimulation: A Contemporary Particularity
You may have already sensed: the vast majority of contemporary consumption is multi-sensory coordinated assault — this differs from ancient times.
- Scrolling a "old-tomato pasta" short video: color (visual) + sound (the cooking BGM) + odor (vaguely drifting from the screen) + taste (the appetite imagination aroused) + tangible (the body wrapped by keyboard and blanket). One single event, five faculties and five sense objects ignited at once. - A partner sprays a new perfume toward you: nose + body receive simultaneously. - Dining at a high-end restaurant: ambient lighting (eye), background music (ear), the presentation of fine dishes (eye), the aroma of the dishes (nose), the taste entering the mouth (tongue), the comfort of the chair (body) — all six faculties wrapped.
Multi-sensory coordination is the mark of the contemporary, not the individual clinging of any one faculty. This means the contemporary awareness practice is not "I restrain one faculty's clinging," but an awakening of all six faculties as a whole — the training of "abiding without abiding" (住而無住) as a total practice.
3. Why Contemporary People Need It
3.1 It Is an Object Intensified by the Technological Age
Before the industrial revolution:
- Sound (apart from human speech, wind, animal sounds, occasional instruments) was low in density; - Odor (apart from the home, everyday objects, seasonal flowers) was low in concentration; - Taste (dependent on seasons, region, family custom) was low in variety; - Tangible (the relation between skin and clothing) changed slowly.
Today, sound is infinitely compressed and copied; odor is precisely blended and delivered on demand; taste is massively stimulated and supplied across seasons; tangible is layer upon layer packaged and industrially customized.
Every contemporary person is a heavily invaded target of the six faculties and six sense objects — but practice itself is needed in every age alike.
3.2 It Is the Target of the Attention Economy
The goal of the contemporary mainstream business model is to compete for attention and desire. How are attention and desire fought over? Through the six faculties and six sense objects.
- An app's notification sound (sound); - A bakery's new product launch (odor + taste + tangible + form); - A song on loop creating an emotional atmosphere (sound + tangible + mental objects); - A perfume brand's sampling event (odor + tangible + sound + human eyes and speech).
Reading these four, you see: modern marketing is not "selling goods"; it is engineering the entry points of the six faculties and six sense objects.
3.3 It Is the Entry Point Where Sensual Craving Directly Manifests
A common agreement from early Buddhism through the schools and the Abhidharma system: when a practitioner wants to leap out of the desire realm, he or she must first know what is pulling him or her. This "being pulled" is most concretely displayed in the clinging of the six faculties to the six sense objects.
You can feel the "I need" behind it:
- I need this coffee — the tongue's sensual craving; - I need silence in my earbuds — the ear's sensual craving; - I need this soft fabric on my body — the body's sensual craving; - I need this familiar scent to come back — the nose's sensual craving.
Behind every "I need" there is a precise attribution to an entry point (入處). Reading to this point is the entrance to "knowing as it really is" (如實知, yathābhūta-jñāna).
3.4 It Is the Starting Point of Practice, Not the Endpoint
This is a topic often flattened: "understanding sound, odor, taste, tangible" is the starting point, not the endpoint.
- Seeing impermanence in sound, odor, taste, tangible — initial awakened observation. - Moving from clinging to non-clinging with respect to sound, odor, taste, tangible — the mind obtains initial loosening. - Moving from "knowing impermanence" to "letting it come and go" with respect to sound, odor, taste, tangible — abiding without abiding.
This is the progression of the practice topic "sound, odor, taste, tangible." Let us be careful: seeing clearly is not letting go; after seeing clearly there is still honest practice, and it is practice that brings about the letting go.
4. Common Misreadings and Clarifications
4.1 "Are These Five Kinds of Sensory Enjoyment?"
Many people understand "色聲香味觸" as "sensory enjoyment" and simplify the scriptures' vigilance toward them into an opposition to enjoyment. No.
The meaning of the classics is not to prohibit enjoyment, but to abide nowhere (住無所住).
Nothing forbids you from listening, smelling, tasting, or touching; it only invites you not to let the mind "abide" there — not to let "I" be crushed by that sense object, not to let the aching place throb densely the instant the object departs.
This is a topic often flattened into the two extremes of "asceticism" or "hedonism." The true middle is knowing as it really is in the present moment — seeing its arising and ceasing, its impermanence, its no-self, its lack of owner.
4.2 "These Five Bad Things?"
Another corresponding deviation: treating sound, odor, taste, and tangible as five bad things, thinking the path requires fleeing them. The Buddha himself walked on alms-round past homes offering flowers and incense; in the Buddha's age, monks wore soft hemp robes and dwelt in naturally comfortable places; the Buddha drank water, smelled incense, tasted food — he never said that flowers and incense are enemies. The enemy of the path is the abiding mind, not the material of odor itself.
4.3 "Do the Five Desires Equal 色聲香味觸法?"
This point needs a bit of clarification. There is mixed usage in popular speech and in scriptural discourse:
- The secular "five desires" (五欲) (as commonly used in the *Dīrghāgama* (《長阿含經》) and *Ekottarāgama* (《增壹阿含經》)) are desire for wealth (財欲), desire for sex (色欲), desire for fame/reputation (名欲), desire for sleep (睡欲), desire for food and drink (飲食欲). - The Buddhist "five sense objects" (五塵) are form, sound, odor, taste, tangible — corresponding to the first five of the six sense objects (the sixth, "dharma-object," being set aside).
These two systems are not the same thing. Equating the secular five desires with 色聲香味觸 is a common slip in popular preaching and should be carefully distinguished. The six sense objects / five dusts speak of the objects of the external sense bases; the secular five desires speak of the specific major domains that stir the ordinary mind — the two categories intersect but are not equal.
4.4 "Does 香 Only Mean Good Odor?"
Some readers think "香" refers only to good scents like sandalwood, aloes, rose. In fact, odor is divided into three equal parts of like, dislike, and neutrality — good odor, bad odor, neutral odor are all odor-domains, all objects of the nose faculty.
Likewise: - Sound does not only mean music or harsh noise — wind howling, leaf rustling, rain, everything the ear faculty encounters is sound; - Taste does not only mean sweet, spicy, bitter — bland, sour, salty, compound flavors are all taste; - Tangible does not only mean skin — all contact between the body and external things is tangible.
4.5 "Just Block Out the Ear, Nose, Tongue, and Body?"
The precepts do impose restrictions at certain levels on sound, odor, taste, and tangible — for example, renunciants do not attend song-and-dance performances, do not apply fragrance, do not drink high-alcohol beverages, do not sit or lie on high or wide beds — but this is the specific norm at the level of the precepts, an auxiliary condition, not the ultimate. The ultimate is still the mind: if the mind still abides in clinging to something, mere behavioral prohibition cannot bring liberation; when the mind no longer abides, the sense object can sometimes even become a blessing.
Prohibition is guarding and protecting, not realization (禁是攝護，不是證解).
4.6 "Listening to High-Class Music Is Achievement?"
A contemporary equation: thinking that ear-faculty purity means hearing pleasant music without being swept away, so "as long as I listen to classical music" I am practicing well. This merely swaps one "form-dust" for another kind of "form-dust," swapping "craving for pleasant sound" for another kind of abiding: "I listen to high-end music, so I have elevated myself."
The true ear-gate practice is: when a song plays, the mind is not carried away by the melody; when silence comes, the mind is not seized by loneliness. Both are practice.
4.7 "Is 觸 the Same as Touch Sensation?"
In Chinese, 觸 and "觸覺" (touch sensation) are close in meaning and often equated. But please distinguish:
- In the twelve sense bases, 觸 is the sense-object that arises when the body faculty meets external matter — a specific conditioned arising as defined by the Sarvāstivāda school: there must be the body faculty and the touched object in contact, plus body-consciousness (touch-consciousness) to constitute "tangible." - It is not merely "touching." - It is the concrete sensation at the point of contact between the body and the external environment — cold, warm, smooth, rough, light, heavy, hunger, thirst, soft, hard, distended, painful. - The classics often link "tangible" with the touch-substance of the "four great elements" (四大) — it is the touch produced by the combination of the four great elements.
4.8 "I Only Address What I'm Most Attached To; the Rest Doesn't Matter?"
A posture tending toward "non-equality": thinking that what is worth practicing is the faculty I cling to most strongly, and the rest can wait.
But in the classical tradition, the correct observation of the six sense bases is equal observation — the six sense bases are equally impermanent, suffering, and no-self. The non-equal observation itself is another kind of clinging — clinging to "which is more important, which is less important." This does not mean practice has no stages (stages do exist), but at the level of "knowing as it really is" in the mind, equal observation is wisdom. So a contemporary practitioner in whom one particular item of the five desires burns hot is often encouraged by the teacher to return to equal observation — to look after all sense objects equally.
4.9 "Seeing Clearly Is Liberation?"
Seeing clearly that the five desires are the five desires, that sound-odor-taste-tangible are sound-odor-taste-tangible, is the starting point of wisdom, not liberation. True "abiding nowhere" requires three things:
- Moral discipline (戒, śīla) — protecting body and speech from entering states that violate the precepts; - Concentration (定, samādhi) — letting the mind settle, able to see into objects; - Wisdom (慧, prajñā) — knowing its impermanence, seeing its no-self, cutting its bonds.
Seeing clearly is not equivalent to having let go; it is the honest practice after seeing clearly that brings about the letting go.
Conclusion: Closing with the "Abiding Nowhere" of the Diamond Sutra
Returning to the instruction from the *Diamond Sutra* that nearly everyone can recite:
「是故，須菩提，菩薩應如是生清淨心：不應住色生心，不應住聲香味觸法生心，應無所住而生其心。」 *"Therefore, Subhūti, the bodhisattva should give rise to a pure mind thus: not abiding in form, give rise to the mind; not abiding in sound, odor, taste, tangible, or mental objects, give rise to the mind; give rise to a mind that abides nowhere."*
The six characters "色聲香味觸法" are the collective name of the six sense objects, and "聲香味觸" stands here alongside "色" and "法" as the full set of objects toward which "abiding nowhere" applies.
Contemporary life has you and me rushing daily through the six faculties and six sense objects:
- The ear hears countless sounds every day — abide nowhere; - The nose smells countless odors every day — abide nowhere; - The tongue tastes countless flavors every day — abide nowhere; - The body contacts countless tangibles every day — abide nowhere; - The eye sees countless forms every day — abide nowhere; - The mind-consciousness clings to countless mental objects every day — abide nowhere.
This "abiding nowhere" is not prohibition; it is "coming and going without defilement" (來去不染).
The object comes; you know it. The object goes; you know it. You do not bind "I" to any object, letting the mind be free in the sea of the six sense objects.
This is the simplest and also the deepest topic when contemporary people encounter the *Diamond Sutra* and the six sense bases section of the *Āgamas*. And it is the farthest point that the four characters "聲香味觸" must travel on the whole path of liberation.
