What This Concept Is About
In the cosmic-evolution picture constructed by the Buddhist scriptures 長阿含經 (*Dīrghāgama*, "Long Discourses") and 中阿含經 (*Madhyamāgama*, "Middle-Length Discourses"), 地味 (pṛthivī-rasa, "earth-taste") is a concept of profound metaphorical depth and Vijñānavāda significance. It is not a mineral in the modern geological sense, but rather an extremely sweet, pure substance with color, fragrance, and flavor that naturally congeals on the ground when the world is first generated at the beginning of a kalpa (劫).
1. The Precise Classical Definition and Physical Characteristics * Causes and Conditions of Generation: After the kalpa of destruction (壞劫) passes and the world is regenerated, the great waters, blown and condensed by the wind, gather a layer of extremely pure condensate on their surface—just as the skin that forms on boiling milk when it cools, or the essence that coagulates when milk is churned. From this, 地味 (earth-taste) is born. * Color, Fragrance, and Taste: Its color is glossy and appealing, like raw ghee and cooked ghee (色如生酥及熟酥色, "its color is like that of raw ghee and cooked ghee"); its taste is as sweet as pure honey or honey-pills (味甜如蜜, 味如蜜丸味, "its taste is sweet as honey, its flavor like honey-pills"). In the 長阿含經 (*Dīrghāgama*), it is also called 甘泉 ("sweet spring," resembling ghee-honey) or 自然地味 ("naturally occurring earth-taste").
2. Core Doctrinal Significance: The Ford from "Feeding on Thought/Joy" to "Solid Food"
地味 occupies an extremely critical position in the entire path of liberation and in the Buddhist worldview—it is the bridge by which sentient beings cross from a non-material state of spiritual nourishment into a state of material bodily consumption (抟食/段食, kavaḍīkāra-āhāra, "solid food").
At the very beginning of the world, the beings who took birth in the human realm came from 光音天 (*Ābhāsvara-deva*, the Heaven of Radiant Sound; rendered as 晃昱天 in the 中阿含經). These beings were originally in a purely apparitional state (化生, upapāduka), possessing a pure and unobstructed mind-made body (意生身, manomaya-kāya) of subtle beauty, with all faculties complete, radiating their own light (身光自照), and endowed with the supernormal power of psychic travel (神足通, ṛddhi-vidhi) enabling them to fly freely through the air. Most importantly, they "fed on thought" (以念為食) or "fed on joy" (以喜為食)—their life-energy came entirely from the meditative bliss and dharma-joy of the mind, requiring no intake of any external matter.
The appearance of 地味 tore a rift in this pure state:
* Step One: Tasting and Craving. A being of facile character or strong greed, by chance, "dipped a finger into this earth-taste and tasted it" (以指抄此地味嘗). Upon tasting it and finding it extremely sweet, craving was instantly activated. For the sake of enjoyment and to avoid the trouble of dipping with a finger, this evolved into scooping with the hand (以手掬) and even grabbing large handfuls to eat (以手撮). The other beings, seeing this, imitated it one after another, sinking into attachment without ever being satisfied. * Step Two: The Body Grows Heavy and Turbid; the Light Goes Out. With the heavy intake of material food (段食), the originally pure and buoyant bodies of these beings underwent drastic physiological degeneration—"the body grew thick, heavy, and hard" (身生轉厚、轉重、轉堅), the muscles became coarse, and the sublime beauty of celestial beings vanished without a trace. Having lost the buoyant body, the supernormal power of psychic travel was likewise lost; they could no longer fly, and could only walk on the ground. At the same time, their innate radiance went out, and the world returned to great darkness. Only then did the sun, moon, stars, day and night, and the seasons naturally come into being. * Step Three: Differentiation of Appearance and the Sprouting of Social Evils. Differences in food intake led to differences in bodily appearance: those who ate little "retained a radiant complexion" (色猶悅澤), while those who ate much "grew coarse and ugly" (顏色粗醜). Beings who had originally been without discrimination thus developed a sense of "self and other": the beautiful ones gave rise to arrogance ("my color is superior, yours is not"), and the ugly ones gave rise to envy and hatred. Comparison, disputation, and contention began to sprout.
3. The Sequential Degeneration of Food and the Decline of Merit
Because beings gave rise to arrogance and contention, this naturally generated 地味 naturally dried up and vanished, and the beings wept and wailed. Thereafter, in accordance with the progressive decline of beings' merit and morality, other substitutes successively appeared in the world, forming a strict sequence of degrading foodstuffs:
1. 地味 (earth-taste; the highest-purity natural condensate, sweet as honey) 2. 地肥／地皮／地膚 (earth-fat / earth-skin / earth-covering; of secondary quality, shaped like thin cakes or the *kanaka* flower, still beautiful in color and flavor) 3. 婆羅 (of yet lower quality, tasting like thick honey-pills) 4. 自然粳米 (naturally grown rice; the end point of the evolution. The rice had to be stored and accumulated, which in turn triggered the division of fields, private property, theft, punishment, and the birth of landowners and the 剎帝利 (kṣatriya) caste, definitively ending the age of the primal kalpa).
The deeper meaning of the earth-taste allegory is this: the material scarcity and class conflict of the world are not inherent to existence, but rather the deterioration of the external environment projected onto the earth's surface by beings' inner greed and the turbidification of consciousness.
A Walk-Through in Daily Life
In the ordinary scenes of modern life, we are almost constantly undergoing the process of "eating earth-taste." The most common mis-mapping is to equate 地味 with some specific vulgar desire (such as binge eating), while overlooking the fact that the core essence of earth-taste is this: consciousness uses an external stimulus as a substitute for life-energy, thereby losing the capacity for inner self-generated stability ("feeding on thought").
Let us walk through this process in a typical modern person's day:
* Scenario One: Waking in the Morning—From "Internal Focus" to "Dipping a Finger to Taste" * The Original State (feeding on thought/joy): In the first seconds after waking, before the mind has sunk into trivial concerns, there is a pure autonomous quality. * Tasting the Earth-Taste: You reach for your smartphone, swipe the screen, and open a social media app or short-video feed. That first glance—"let me check the news / scroll the feed"—is precisely "dipping a finger into this earth-taste and tasting it". The tiny dopamine release of that instant is as sweet as a honey-pill. * Clarifying the Common Mis-mapping: People assume that "only addiction to gaming or reckless credit-card spending counts as craving." In fact, the moment you begin to depend on external stimulation (information, praise, sensational news) to feel alert and settled, you have already left "feeding on thought" and taken the first step of eating earth-taste.
* Scenario Two: Work and Commute—"Scooping with the Hand" and "The Body Grows Heavy" * Large-Mouth Consumption: What began as a taste test gradually becomes a habit. You unconsciously scroll through short videos in succession, endlessly devour fragmentary information, or rely on excessive coffee and sugary milk-tea to maintain excitement. This is "scooping with the hand, gradually becoming solid food". * Physical and Mental Degeneration: Sustained external stimulation makes your attention and mind extremely viscous and heavy. The originally buoyant thinking (the celestial sublime form, flying through the air with psychic power) disappears, replaced by distracted attention, brain fog, and physical-mental exhaustion ("the body grows thick, heavy, and hard"). The clarity that was originally within the mind (one's own light) is extinguished by the clamor of the external world, and one sinks into the great darkness of anxiety and confusion.
* Scenario Three: Social Life and the Workplace—"Differentiation of Appearance" and "Arrogance and Envy" * Comparison Arises: On social media feeds or in workplace performance reviews, some people display a superior lifestyle or higher position ("those who ate little earth-taste retain a radiant complexion"), while others feel exhausted, disheveled, and deprived ("those who ate much earth-taste grow coarse and ugly"). * Moral and Relational Breakdown: Those with resources develop a hidden sense of superiority and arrogance ("my color is superior, yours is not"), while those at a disadvantage develop envy, anxiety, and hostility. Previously harmonious peer or intimate relationships become "disputes over appearance"—mutual rivalry and scheming.
* Scenario Four: Resource Scarcity and the Lament of "Alas, the Earth-Taste" * Resource Depletion and Substitution: When the pleasure delivered by a platform diminishes, or the stimulation of a certain form of consumption hits diminishing returns ("the earth-taste is extinguished"), people do not reflect on craving itself, but instead fall into panic and regret ("Alas, the earth-taste! Alas, the earth-taste!"). They then go looking for substitutes with slightly weaker stimulation (earth-fat, earth-covering, rice), until life is entirely consumed by the unceasing rat race of defensive competition and asset hoarding (naturally grown rice and the privatization of fields).
Why Contemporary People Need It
Contemporary people live in an era of "extreme earth-taste surplus." Algorithms, enormously abundant material supply, and refined consumerism are, in essence, a gigantic "hyper-stimulating earth-taste" manufactured by human civilization.
1. Dismantling the Myth That "Material Abundance Equals Evolution" Modern civilization habitually views human history as a linear evolution from lower to higher, but the scriptural narrative of earth-taste offers a profoundly Vijñānavāda perspective: the deepening of material intake is essentially a compensation for the degeneration of the spiritual dimension of life. Contemporary scientific research (such as the mechanism of dopamine receptor desensitization) also confirms this: when a person excessively depends on external high-sugar, high-stimulation foods or streams of information, the brain's own capacity to produce endorphins and endogenous dopamine declines. This corresponds strikingly to the scriptural statement that "those who ate earth-taste lost their psychic powers and bodily radiance and had to depend on the external light of the sun and moon".
2. Re-examining the Quality of "Spiritual Food" Buddhism divides food into four kinds: 段食 (solid food, kavaḍīkāra-āhāra), 觸食 (contact-food, sparśa-āhāra), 意思食 (volition-food, manasañcetanā-āhāra), and 識食 (consciousness-food, vijñāna-āhāra). Earth-taste is the beginning of solid food. Contemporary people are excessively overfed on material solid food, yet extremely impoverished in "volition-food" and "dharma-joy." Understanding the concept of earth-taste can remind contemporary people to recover the capacity of "feeding on thought" (nourishing oneself inwardly through right mindfulness, concentration, and insight) and to stop endlessly demanding stimulation from outside.
*The Boundaries and Points of Contact with Contemporary Science*:
The neuroscientific explanation of "dopamine tolerance" and "reward-system degradation" can indeed help contemporary people understand the physiological mechanism by which "eating earth-taste causes the body to grow heavy and thick and raises the pleasure threshold." However, the neuroscientific analogy is by no means equivalent to Buddhist doctrine. Science treats dopamine as a molecular chemical reaction, confined to the physical layer of neurons; whereas the "earth-taste" of the Buddhist scriptures is a cosmogonic narrative of consciousness-only manifestation (唯識所現) and karmically shared perception (業力共感)—it concerns how the ignorance and craving of sentient beings shaped the fundamental direction of the entire physical world and social structure, a dimension that current experimental science cannot cover or prove.
Common Misreadings and Clarifications
* Misreading One: Equating 地味 with "poison" or "something evil," believing that Buddhism advocates asceticism and aversion to matter * Clarification: Earth-taste itself arises naturally; its color, fragrance, and flavor are all good, and it carries no original sin. The scriptures clearly state that what caused the great darkness of heaven and earth and the disappearance of bodily radiance was not the substance of earth-taste itself, but beings' "craving," "delight in," and "insatiability" toward it. Buddhism never denies the sweetness of material things; it is, however, extremely vigilant about consciousness's 粘著 (attachment) and 攀緣 (clinging) to matter.
* Misreading Two: Understanding "feeding on thought" as fasting, breatharianism, or Daoist immortality techniques * Clarification: In the Buddhist path of liberation, "feeding on thought" or "feeding on joy" is the life-state of the beings of the higher form-realm heavens such as 光音天 (*Ābhāsvara-deva*), arising from extremely deep meditative absorption (the nourishment of the samādhi-waters of the first through third dhyānas). In the practice of the desire-realm human path, one is not required to forcibly fast within the coarse physical body; rather, the practitioner is to consume solid food "as if eating the flesh of one's own child" (如食子肉)—eating with right mindfulness and right knowing, understanding that food merely sustains the body for the sake of cultivating the true within the provisional, without giving rise to craving or comparison.
* Misreading Three: Assuming this is merely an ancient, absurd creation myth with no relevance to actual practice * Clarification: In the framework of the Āgamas and the Abhidharma (阿毗達磨), the destruction and generation of the cosmos is an unceasing cycle of saṃsāra. The story of earth-taste is not an ancient legend but a psychological fact re-enacted in consciousness at every moment: whenever you reach for something out of inner emptiness (dipping a finger to taste), from the first tiny stirring of greed, to being carried away by desire (gulping down large handfuls), to giving rise to arrogance and hatred through comparison of gain and loss (differentiation of appearance), and finally to feeling pleasure diminish and body-mind exhausted (the extinction of earth-taste)—this entire twelvefold-chain-of-dependent-origination (十二因緣)-style evolution is precisely the most profound warning for liberation that the concept of "earth-taste" offers to modern people.
