The Middle Way of True Observation
Named in Part 4 for the first time, the middle way of true observation is now unfolded in full: every pair of extremes named and set aside in turn, dependent origination read forward into suffering and in reverse into its ending, and — in the sūtra's most philosophically striking move — a direct warning that emptiness itself must never become one more fixed view to lean on.
Every Pair of Extremes, and Dependent Origination Both Ways
「復次迦葉！真實觀者，謂不觀色有常無常，亦不觀痛想行識有常無常，是謂中道真實觀法。復次迦葉！云何為真實觀諸法？謂不觀地有常無常，亦不觀水火風界有常無常，是謂中道真實觀法。
「復次迦葉！有常是一邊，無常為二邊，此二中間無色，不可見亦不可得，是謂中道真實觀法。有我是一邊，無我為二邊，此二中間無色，不可見亦不可得，是謂中道真實觀法。有真實心者是謂一邊，無真實心者是為二邊，無心無思無意無識，是謂中道真實觀法。如是不善法、世間法、有諍法、有漏法、有為法、有穢污法，是謂一邊；如是善法、出世間法、無諍法、無漏法、無為法、白淨之法，是為二邊，此二中間，無所有亦不可得，是謂中道真實觀法。有者是一邊，無者為二邊，此二中間，無所有亦不可得，是謂中道真實觀法。
「復次迦葉！我為汝說，無明緣行，行緣識，識緣名色，名色緣六入，六入緣更樂，更樂緣痛，痛緣愛，愛緣取，取緣有，有緣生，生緣老死、苦惱、憂悲、啼泣，如是生大苦陰。無明已盡則行盡，行盡則識盡，識盡則名色盡，名色盡則六入盡，六入盡則更樂盡，更樂盡則痛盡，痛盡則愛盡，愛盡則取盡，取盡則有盡，有盡則生盡，生盡則老死、苦惱、憂悲皆盡，如是滅大苦陰。無有此二，亦無二行，中間可知，是謂中道真實觀法。如是行行盡，識、名色、六入、更樂、痛、愛、取、有、生、老死老死盡，無有此二，亦無二行，中間可知。如是迦葉！是謂中道真實觀諸法也。」
"Furthermore, Kāśyapa! True observation means not observing form as permanent or impermanent, nor observing sensation, perception, mental formations, or consciousness as permanent or impermanent — this is called the middle way of true observation. Furthermore, Kāśyapa, what is the true observation of all dharmas? It means not observing the earth-element as permanent or impermanent, nor observing the elements of water, fire, and wind as permanent or impermanent — this is called the middle way of true observation.
"Furthermore, Kāśyapa! Permanence is one extreme, impermanence is the second extreme; between these two there is no form at all, nothing that can be seen or found — this is called the middle way of true observation. A self is one extreme, no-self is the second extreme; between these two there is no form at all, nothing that can be seen or found — this is called the middle way of true observation. Having a real, true mind is one extreme, having no real, true mind is the second extreme; no mind, no thought, no intention, no consciousness — this is called the middle way of true observation. Just so, unwholesome dharmas, worldly dharmas, contentious dharmas, contaminated dharmas, conditioned dharmas, and defiled dharmas are one extreme; and wholesome dharmas, supramundane dharmas, uncontentious dharmas, uncontaminated dharmas, unconditioned dharmas, and pure dharmas are the second extreme — between these two there is nothing at all, nothing that can be found — this is called the middle way of true observation. Existence is one extreme, non-existence is the second extreme; between these two there is nothing at all, nothing that can be found — this is called the middle way of true observation.
"Furthermore, Kāśyapa! I shall explain this for you: ignorance conditions volitional formations, volitional formations condition consciousness, consciousness conditions name-and-form, name-and-form conditions the six sense-fields, the six sense-fields condition contact, contact conditions sensation, sensation conditions craving, craving conditions grasping, grasping conditions becoming, becoming conditions birth, and birth conditions old age, death, suffering, grief, sorrow, and lamentation — thus arises this great mass of suffering. When ignorance is exhausted, volitional formations are exhausted; when volitional formations are exhausted, consciousness is exhausted; when consciousness is exhausted, name-and-form is exhausted; when name-and-form is exhausted, the six sense-fields are exhausted; when the six sense-fields are exhausted, contact is exhausted; when contact is exhausted, sensation is exhausted; when sensation is exhausted, craving is exhausted; when craving is exhausted, grasping is exhausted; when grasping is exhausted, becoming is exhausted; when becoming is exhausted, birth is exhausted; when birth is exhausted, old age, death, suffering, grief, and sorrow are all exhausted — thus this great mass of suffering is extinguished. There is neither of these two, nor any twofold process — what lies between can be known — this is called the middle way of true observation. Just so with volitional formations, consciousness, name-and-form, the six sense-fields, contact, sensation, craving, grasping, becoming, birth, old age and death, and their exhaustion — there is neither of these two, nor any twofold process; what lies between can be known. Just so, Kāśyapa, is the middle way of truly observing all dharmas."
This is one of the earliest attested Mahāyāna statements of a method this site's Middle Treatise would later develop into a full philosophical system — but the two texts argue for the same conclusion in almost opposite ways. Nāgārjuna's treatise builds toward each rejection of an extreme through sustained logical reductio, chapter by chapter; this sūtra simply states each pair of extremes and asserts, without argument, that "between these two there is nothing at all, nothing that can be found" (此二中間，無所有亦不可得), repeated as a refrain nine times across this single passage. What the repetition itself teaches is a habit of attention rather than a proof — permanence and impermanence, self and no-self, even wholesome and unwholesome dharmas are each treated as a pair to be set down together, never as one safe side to retreat to once the other has been refuted. That a "wholesome dharma" appears here as one extreme, exactly parallel to an unwholesome one, is easy to read past and worth pausing on: the teaching does not let "the good" become a resting place either.
The sūtra then applies this identical framework directly onto dependent origination — a teaching usually presented, including elsewhere on this site, as a literal causal chain to be run forward into suffering and reversed into liberation. Here the forward and reverse sequences are both stated in full, and then immediately relativized: "there is neither of these two, nor any twofold process" (無有此二，亦無二行). Arising and ceasing are not exempted from the middle way just because they describe how liberation actually happens; they too are two extremes with nothing fixed lying between them, "known" (可知) rather than seen or grasped as objects in their own right.
Why Emptiness Itself Must Never Be Clung To
「復次迦葉！中道真實觀諸法者，不以空三昧觀諸法空，諸法自空故。不以無想三昧觀諸法無想，諸法自無想故。不以無願三昧觀諸法無願，諸法自無願故。不以無行觀諸法無行，諸法自無行故。不以無起觀諸法無起，諸法自無起故。不以無生觀諸法無生，諸法自無生故。不以如觀諸法如，諸法自如故。是謂中道真實觀法。不以無人觀諸法空，諸法自空故。如是本空末空，現在世空，當令依空莫依於人。若有依空，倚此空者，我說是人遠離此法。如是迦葉！寧猗我見積若須彌，不以憍慢亦不多聞而猗空見者，我所不治。譬如良醫應病與藥，病去藥存，於迦葉意所趣云何，此人苦患寧盡不耶？」答曰：「不也！世尊。」「所以者何？藥在體故。如是迦葉！空斷一切見，若有猗空見者，我所不治，亦復如是。
「譬如有人畏於虛空啼泣而說：『今當為我去此虛空！』於迦葉意所趣云何，寧能去不？」答曰：「不也。世尊！」「如是迦葉！若畏空者，我說此人甚為狂惑。所以者何？眾生造空而彼畏之。譬如畫師作鬼神像即自恐懼。如是迦葉！諸凡愚人自造色聲香味細滑之法，輪轉生死不知此法，亦復如是。譬如幻師，化作幻人而食幻師，無有真實。如是迦葉！修行比丘，隨所思惟一切虛偽，而不真實無有堅固，亦復如是。譬如二木因之更生火而燒彼木。如是迦葉！因真實觀生無漏慧根，而彼即燒於真實觀，亦復如是。譬如然燈諸冥悉除，此闇無所從來亦無所至，不從東方、南方、西方、北方而來，亦不至彼。如是迦葉！智慧已生、無智即滅，此無智者，無所從來、亦無所至。如是迦葉！燈無此念：『我當除冥。』而燈然者諸冥即除，燈闇俱空，不可獲持無作無造，亦復如是。譬如迦葉！百歲冥室若然燈者，彼闇頗有是念：『我當住此而不去。』耶？」答曰：「不也。世尊！此闇必滅。」「如是迦葉！若有眾生百千劫中造作結行，以一正觀無漏智燈即得除盡，亦復如是。」
"Furthermore, Kāśyapa! One who truly observes all dharmas by the middle way does not use the samādhi of emptiness to observe dharmas as empty, since dharmas are empty of themselves. One does not use the samādhi of no-marks to observe dharmas as markless, since dharmas are markless of themselves. One does not use the samādhi of no-aspiration to observe dharmas as free of aspiration, since dharmas are free of aspiration of themselves. One does not use non-activity to observe dharmas as inactive, since dharmas are inactive of themselves. One does not use non-arising to observe dharmas as unarisen, since dharmas are unarisen of themselves. One does not use non-birth to observe dharmas as unborn, since dharmas are unborn of themselves. One does not use suchness to observe dharmas as suchness, since dharmas are suchness of themselves. This is called the middle way of true observation. One does not use the absence of a person to observe dharmas as empty, since dharmas are empty of themselves. Just so, they were empty at the beginning, empty at the end, and empty in the present — one should rely on emptiness itself, not rely on any person who asserts it. If there is one who relies on emptiness, leaning on this emptiness as though it were something to grasp, I say that this person has strayed far from this very teaching. Just so, Kāśyapa! One might sooner cling to a view of self piled as high as Mount Sumeru than lean, without pride and without wide learning, on a view of emptiness — for one who leans on a view of emptiness, I say, cannot be cured at all. It is like a good physician who gives medicine matched to the illness, and once the illness is gone, the medicine still remains in the body — what do you think, Kāśyapa, has this person's suffering and affliction truly come to an end?" He answered: "No, World-Honored One." "Why is this? Because the medicine still remains in the body. Just so, Kāśyapa, emptiness severs every view — and if one leans on a view of emptiness itself, I say this person cannot be cured either, for the very same reason.
"It is like a person who fears empty space, weeping and saying: 'Now, take this empty space away from me!' What do you think, Kāśyapa — could it ever really be taken away?" He answered: "No, World-Honored One!" "Just so, Kāśyapa, if one fears emptiness, I say this person is utterly deluded. Why is this? Because it is the being himself who has conjured the emptiness, and then fears what he himself has conjured — like a painter who paints an image of a ghost or spirit, and is then frightened by it himself. Just so, Kāśyapa, every foolish, ordinary person conjures for himself the dharmas of form, sound, smell, taste, and touch, and, turning through the cycle of birth-and-death, fails to recognize this very fact — it is exactly the same. It is like a conjurer who conjures a phantom person, who then devours the conjurer himself — none of it is real at all. Just so, Kāśyapa, a monk in practice, whatever he thinks and considers, is entirely false, without any reality, without any solidity — it is exactly the same. It is like two pieces of wood, which, rubbed together, generate a fire that then burns up that very wood. Just so, Kāśyapa, the uncontaminated root of wisdom, generated in dependence on true observation, then burns away that very true observation — it is exactly the same. It is like lighting a lamp, whereby every darkness is entirely removed — yet this darkness came from nowhere, and goes nowhere; it did not come from the east, the south, the west, or the north, nor does it go to any of them. Just so, Kāśyapa, once wisdom has arisen, ignorance is thereby extinguished — and this ignorance likewise came from nowhere, and goes nowhere. Just so, Kāśyapa, the lamp itself has no thought that says, 'I shall remove the darkness' — and yet, once the lamp is lit, every darkness is removed all the same; lamp and darkness are both empty, unable to be seized or held, without agent and without maker — it is exactly the same. It is like this, Kāśyapa: if a lamp is lit within a room that has been dark for a hundred years, does that darkness have any thought at all, saying, 'I shall remain here and not depart'?" He answered: "No, World-Honored One — that darkness will surely be dispelled." "Just so, Kāśyapa, even if beings have, across hundreds of thousands of kalpas, built up bonds and afflictions through their own actions, all of it can likewise be entirely removed by the single lamp of uncontaminated wisdom born from right observation — it is exactly the same."
The claim that one might sooner cling to a view of self "piled as high as Mount Sumeru" than lean on a view of emptiness is one of the sūtra's most startling reversals of ordinary Buddhist priority. Self-view is treated everywhere else in this literature as the root affliction, the very thing every other teaching exists to dismantle — yet here it is named the more curable of the two errors. The physician simile makes the reasoning explicit: a self-view is at least recognized as a disease still present in the body, something a further antidote can still address; a person who has turned emptiness itself into a possession has mistaken the antidote for a cure already complete, and there is no second medicine left to give someone who believes their treatment is finished. This is the same warning this site's Diamond Sūtra gives in its own well-known raft simile — "the Dharma itself should be let go, how much more so what is not the Dharma" — stated here through a physician instead of a raft, and with a sharper edge: not merely that the teaching must eventually be released, but that clinging to it is actively harder to treat than the original disease.
The two-pieces-of-wood simile pushes this same warning one step further than the raft image usually does. A raft is simply set down once the far shore is reached; here, the wisdom generated by true observation is said to actively "burn away" (燒) the very observation that produced it, the way friction-fire consumes its own fuel. Nothing is left standing once the process completes — not the extremes that were refuted, and not the observation that refuted them either. The lamp-and-darkness sequence that follows supplies the sūtra's own account of why this is not nihilism: darkness genuinely is dispelled, decisively and without exception, even though it never came from anywhere and goes nowhere, and even though the lamp holds no intention to remove it. Wisdom's real effect on affliction accumulated across "hundreds of thousands of kalpas" is asserted just as firmly as the emptiness of every term used to describe it — the sūtra does not treat these two claims as being in any tension at all.
Part 5 Complete
This closes Part 5: every pair of extremes named and dissolved, dependent origination read both ways through the same lens, and the sūtra's sharpest warning yet — that emptiness itself, mishandled, is harder to cure than the self-view it was meant to treat. Part 6 turns to a gentler register: how a bodhisattva's own dharma-body arises out of affliction rather than apart from it, and why this makes every bodhisattva a true child of the Buddha.
