What This Concept Is Saying
Let us first raise the *huàtóu* (話頭, "word-head")—the meditative question—for examination.
In the Sòng dynasty Chan tradition, there is a famous *gōng'àn* (公案, "public case") known as the "Bamboo Slapper Story." The master holds up a bamboo slapper—the kind of flat bamboo strip used in ancient times for combing hair and also as an instrument of admonition in meditation halls—and asks the student: "If you call it a bamboo slapper, you 'touch' it; if you do not call it a bamboo slapper, you 'turn your back' on it. Tell me: what do you call it?"
This question, simple as it appears, is in fact a trap—and a carefully designed one. The question itself corners you: if you say "this is a bamboo slapper," you have "touched" it—*chù* (觸, "to touch") means to correspond, to accord, and you have fallen into an affirmation of it; if you say "this is not a bamboo slapper," you have "turned your back" on it—*bèi* (背, "to turn one's back") means to deviate, to go against, and you have fallen into a negation of it. No matter what you say, you stand on one of the two sides. What Chan demands, precisely, is "both back and touch are negated" (*bèichù jù fēi*, 背觸俱非)—neither the affirmation nor the negation of the two sides is the answer.
Here a most common misunderstanding must be clarified: the "back" in "back and touch" (背觸) is not the back of the body, but the back of deviation—turning away, going against. The classical entry's phrase "the bodily tactile object as felt by the back" is, doctrinally speaking, an extension of the character *bèi*: when you say "do not call it a bamboo slapper," you deviate from its manifest presence, just as a tactile object felt by the back of the body is vague, unclear, and ungraspable. But this is not the center of gravity of the concept "back and touch." The center of gravity lies in the binary dilemma set up by the Bamboo Slapper Story: is touch right and back wrong? No. Is touch affirmation and back negation? Also no. The framework of the two sides itself is what you must leap out of.
The full structure of this concept must be seen from three levels:
First level: Touch—the trap of affirmation. When you point at the bamboo slapper and say "this is a bamboo slapper," you have completed a judgment. The judgment itself is not wrong, but it has turned the bamboo slapper into an "object"—a thing defined by you, grasped by you, placed by you into a conceptual grid. You feel you know it; you know what it is; so you feel "at ease" with it. But Chan says: this "being at ease" is precisely the problem. Because what you know is not the bamboo slapper itself, but the concept "bamboo slapper" in your mind. You are dealing with concepts, not with the immediate, living bamboo slapper that is, at this very moment, in your hand.
Second level: Back—the trap of negation. You say "this is not a bamboo slapper," trying to find a way out through negation. But negation is still a form of affirmation—you have affirmed the judgment that "it is not a bamboo slapper." Negation has not jumped out of the framework of judgment; it has merely changed direction within the framework. Like a prisoner who walks from the east wall of his cell to the west wall, thinking he has "advanced," when he is still in the cell. Chan calls this "back"—you have turned your back on the manifest presence of the bamboo slapper and hidden yourself in another concept.
Third level: Both back and touch negated—the dissolution of the two sides. This is the true direction of the concept. Neither affirm nor negate; neither cling to "is" nor cling to "is not." But this "both negated" is not the abandonment of "wanting neither," but the direct acceptance of "transcending both"—before you say "is" or "is not," at the very moment when judgment has not yet arisen, what is the relationship between you and the bamboo slapper? Not cognition, not judgment, not naming, but pure, direct, undifferentiated experience itself. You hold it, you see it, and there is no conceptual barrier between you and it. This state, Chan calls "direct acceptance" (*zhíxià chéngdāng*, 直下承當).
The entire practice-logic of this concept is to make you see: your suffering, your confusion, your anxiety—most of it comes not from things themselves, but from your judgments about things. You are trapped between "is" and "is not," trapped between "should" and "should not," trapped between "good" and "bad"—and true freedom is not choosing the right side, but leaping out of the framework of the two sides altogether.
A Walk-Through in Everyday Life
Let us take this Bamboo Slapper Story and walk it through contemporary life.
Scene one: Scrolling your phone late at night.
You pick up your phone. The screen lights up. A thought arises: "I should go to sleep." Immediately another thought follows: "Watching a bit more won't hurt." You are pulled between these two thoughts. The first thought is "back"—you deviate from the immediate phone experience, negating the present moment with "I should sleep"; the second thought is "touch"—you go along with the phone's allure, affirming the present moment with "a bit more." But note: whether "back" or "touch," you are judging—judging what you should or should not do at this moment, judging whether the phone is good or bad, judging whether you are disciplined or indulgent. You have never truly been *with* the activity of "looking at the phone."
What is "both back and touch negated" here? It is not not-looking at the phone, nor is it indulging yourself in looking. Rather, it is that at the instant you become aware that "I am looking at the phone," you set down the judgment of "should or shouldn't," and simply see: the finger is swiping, the eyes are chasing the light, and a voice in the mind is saying "one more video." You see all of this happening, but you do not stand on either side of "should" or "should not." This seeing itself is direct acceptance—you have neither negated the act of looking at the phone nor affirmed it; you are simply with it.
But here is where most people misproject: many take "both negated" to mean "then I'll just keep watching, no more agonizing." That is not "both negated"—that is "touch"—you are merely using "not agonizing" to rationalize "keep watching." The true "both negated" is that seeing itself, not the choice you make after seeing.
Scene two: "This person is so annoying" at work.
There is a colleague in the office whose way of speaking makes you deeply uncomfortable. Your mind begins to operate automatically: Is he right or wrong? Is he targeting me? Should I snap back?—These are all judgments. Saying "he is so annoying" is "touch"—you have affirmed your aversion; saying "I shouldn't find him so annoying" is "back"—you have negated your aversion. But both directions trap you: the former traps you in anger, the latter traps you in self-reproach.
The "both back and touch negated" walk-through: the next time you hear him speak, can you refrain from judging "annoying" or "should like," and instead directly experience that moment—the sound arrives, your chest tightens, your breath becomes shallow, some memories flash through your mind. These are all direct sensory experiences, the reality before concepts arise. You do not need to "like" him, nor do you need to "not find him annoying"; you only need to be with this present moment. This "being with" neither affirms nor negates your aversion, yet it lets you walk out of the prison of aversion.
Scene three: "Do you even love me?" in intimate relationships.
This is perhaps one of the deepest fixations of contemporary people. You ask your partner: "Do you love me?" He says "yes," and you believe it—this is "touch"; you take his words as a certain answer. A moment later you doubt: "Is he just humoring me?"—this is "back"; you negate his just-given response. And so you swing back and forth between "belief" and "doubt," like a pendulum, never at peace.
"Both back and touch negated" is not telling you not to ask the question, nor is it telling you to believe blindly without discernment. It is telling you to see: your understanding of "love" is a concept. The word "love" does not point to a fixed thing. When you treat "love" as an object that can be measured, verified, and grasped, you are doomed to suffer—because love is not an object; love is a dynamic process, the sum of countless moments of interaction. When you set down the judgment "does he love me or not" and simply are with him in this moment—he is speaking, his eyes are looking at you, his hand is holding yours—what you experience is not the concept "love," but the living connection itself. This connection is neither "love" nor "not-love," but it is more real than either word.
Scene four: "Why is my child so disobedient?" in parenting.
The child is rolling on the floor, crying. Your mind immediately starts judging: "Why is this child so disobedient?" "Have I failed as a parent?" "Should I be strict or gentle?"—Every thought is a judgment, and every judgment pulls you away from the crying child right in front of you. Saying "the child is disobedient" is touch; saying "I shouldn't think of him as disobedient" is back; but you have never truly been with this crying child.
The "both back and touch negated" walk-through: you crouch down and see the child's face flushed red, tears sliding from the corners of his eyes; you hear his piercing cry; you feel your own heartbeat quickening. These—the face, the tears, the sound, the heartbeat—are all present-moment experiences, the reality before concepts arise. You have neither negated the judgment "the child is disobedient" nor affirmed it; you have simply stepped out of that judgment and returned to the living little person right there, experiencing a vast emotion. Perhaps you will still take action—comforting him, reasoning with him, or setting boundaries—but that action no longer arises from the judgment "he is disobedient"; it emerges naturally from present-moment seeing.
Why Contemporary People Need It
Our era may be the one with the highest density of judgment in human history.
You open your phone: algorithms are judging what you like. You scroll to a news item: the comment section is judging whether this event is good or bad. You post on social media: everyone is judging whether you are a "winner in life" or "showing off." You open a map app: it is judging which route you should take. You open a food-delivery app: it is judging whether you want something salty or sweet today. You live in endless judgments, and the vast majority of these judgments are not made by you—they are made by others, by machines, by the collective unconscious of the social network.
You are surrounded by countless "touches": this is good, that is bad, this is right, that is wrong, this is worthwhile, that is not. You are also held hostage by countless "backs": I shouldn't think this way, I shouldn't act this way, I shouldn't be this kind of person. You are exhausted from running between "touch" and "back," like a person leaping between two waterfalls—no matter which side you jump to, you are soaked through.
The gift "both back and touch negated" offers contemporary people is not another judgment—"letting go of judgment is the right thing"—that would still be "touch." It offers something more fundamental: you do not have to stand on any side. You need not take a position on everything, need not have an answer to every question, need not react to every stimulus. You can let judgments arise, watch them, and let them pass—like watching clouds drift across the sky: you need not grab hold of every cloud, nor chase every cloud away.
This has common ground with what psychology calls "cognitive defusion": learning to keep distance from thoughts, not taking thoughts as facts. But "both back and touch negated" goes deeper—it does not merely have you "observe thoughts"; it has you see: even the position of "observer" itself is something you have constructed. When you stand in the position of "I" and observe thoughts, you still have the duality of "I" and "thought." What "both back and touch negated" asks you to set down is precisely this duality itself.
Why do contemporary people need it? Because the core ailment of contemporary life is judgment overload. You are swept along by too many "ises" and "is-nots," crushed by too many "shoulds" and "should-nots"; you have lost the capacity for direct contact with things—you see a flower, and the first thought is "what kind of flower is this"; you eat a meal, and first you photograph it for social media; you chat with a friend, and first you think "what does he mean by that." All your experience is mediated by concepts; you live in a world covered in layers of labels, and the real world—the world that is already present before judgment arises—this you can no longer see.
"Both back and touch negated" is what brings you back to that world.
Common Misreadings and Clarifications
Misreading one: "'Back and touch' means 'having no position.'"
This is the most common and most dangerous misreading. Some people understand "both back and touch negated" as a slick neutralism—taking no stand, joining no side, anything goes. This is not "both back and touch negated"; this is "touch"—you have taken a stand on the position of "choosing nothing," and you use "not choosing" to cover the fear of not daring to choose.
The true "both back and touch negated" is not the absence of a position; it is that the position no longer arises from concepts but emerges naturally from present-moment insight. An awakened Chan master's conduct is clearer, more decisive, more resolute than anyone's—but his decisiveness does not come from the binary judgment of "should" and "should not"; it comes from direct insight into the present moment. He is not trapped by "back and touch," but it is not that he has no "back and touch"—it is that after transcending "back and touch," he returns into "back and touch," responding to each present situation with each present moment of awareness.
Misreading two: "'Back and touch' is a unique Chan device, unrelated to ordinary life."
This is probably people being frightened off by the mystique of Chan *gōng'àn*. The language of the cases is indeed obscure, but what they point to is not a mystical realm; it is the most ordinary daily experience. Every day you have countless moments of being in a state where "judgment has not yet arisen"—the instant when the temperature of the tea enters your mouth before "good" or "not good" arises; the instant when the color of the sunset enters your eyes before "beautiful" or "mediocre" arises; the instant when the sound of a child's laughter enters your ears before "adorable" or "noisy" arises. These instants are the entrance to "both back and touch negated." It does not ask you to abandon daily life; on the contrary, it asks you to return to daily life—to return to the naked life that exists before it is covered over by concepts.
Misreading three: "'Back and touch' means 'thinking of nothing.'"
Many practitioners understand "both negated" as "thoughts stopping"—the mind goes blank, nothing at all. This is a serious technical error. What Chan means by "both back and touch negated" is not the stopping of thoughts, but the stopping of attachment to thoughts. Thoughts still arise, judgments still occur—if thoughts truly stopped, you would not even recognize the characters "bamboo slapper," so what would "acceptance" even mean? The "acceptance" in "direct acceptance" is precisely your capacity, at the moment a thought arises, not to be carried off by it—you see the thought "this is a bamboo slapper," and you also see the thought "this is not a bamboo slapper," but you neither cling to the former nor push away the latter; you let them arise, abide, and dissolve, while you remain at the center of awareness, never swept away by either side.
Misreading four: "'Back' means 'the back of the body.'"
This is the most direct textual misreading, and an error found in some contemporary popular explanations. The classical entry's phrase "the bodily tactile object as felt by the back" refers to a certain association of the character *bèi* at the level of bodily experience—when you say "this is not a bamboo slapper," you are like sensing something with your back: the perception is vague, indirect, uncertain—but this is not the center of gravity of the concept. The center of gravity is always the pair "turning away" and "according with." If you understand this *bèi* as the body's back, you have completely missed the point of the Bamboo Slapper Story.
Finally, return to that phrase "direct acceptance."
"Both back and touch negated" does not tell you to "do nothing." Quite the opposite: it lets you see, in the crack between binary judgments, that awareness which has never left you. This awareness is not increased by your saying "this is a bamboo slapper," nor decreased by your saying "this is not a bamboo slapper." It has always been there, beneath all your judgments, emotions, anxieties, and confusions—unmoving, as it is.
One day, when you are cornered by a thorny problem at the office, or tormented late at night in your bedroom by a thought you cannot put down, you suddenly remember the master holding up the bamboo slapper, remember his sudden shout of interrogation—and perhaps you pause, not because you have found an answer, but because you have seen: that problem itself was manufactured by your own judgment. And you—you do not need to stand on any side to be with it.
This is the whole of what "back and touch" has to give you. It is not an answer; it only lets you see: you have never been in a prison—the prison you think you are in was built by yourself, brick by brick, out of "is" and "is not." Put down the hand that is building the wall, and you are already outside.
