Why the Heterodox Theories of Causation Fail
The sūtra turns from its own architecture of mind to a direct critique of rival theories of how anything comes to exist at all — a broken vessel that cannot hold water again, a scorched seed that will never sprout, and, most memorably, the claim that if effects could really arise from "the coming together of three conditions" without an intrinsic cause, then a tortoise ought to grow hair and sand ought to yield oil. Having dismantled these positions, the Buddha turns to the positive teaching that replaces them: seeing every dharma as like a cloud, a whirling firebrand, a city of gandharvas, an illusion, a mirage, the moon in water, or a dream — the insight that carries a bodhisattva, by stages, through the vajra-like samādhi and into the Tathāgata's own body.
The Broken Vessel, the Scorched Seed, and the Tortoise's Hair
「復次，大慧！妄想三有苦滅，無知愛業緣滅，自心所現幻境隨見。今當說。大慧！若有沙門婆羅門，欲令無種有種因果現，及事時住，緣陰界入生住，或言生已滅。大慧！彼若相續、若事、若生、若有，若涅槃、若道、若業、若果、若諦，破壞斷滅論。所以者何？以此現前不可得，及見始非分故。大慧！譬如破瓶，不作瓶事；亦如焦種，不作牙事。如是，大慧！若陰界入性，已滅今滅、當滅，自心妄想見無因故，彼無次第生。大慧！若復說無種有種識，三緣合生者，龜應生毛，沙應出油。汝宗則壞，違決定義。有種無種說有如是過，所作事業，悉空無義。大慧！彼諸外道，說有三緣合生者，所作方便因果自相，過去、未來、現在，有種、無種相。從本已來成事相承，覺想地轉，自見過習氣，作如是說。如是，大慧！愚癡凡夫，惡見所害，邪曲迷醉，無智妄稱一切智說。
"Furthermore, Mahāmati! The suffering of the three realms of existence born of false thought ceases, and ignorance, craving, and the conditions of karma cease, once one sees, in accordance with reality, that these are illusory realms manifested by one's own mind. I will now explain this. Mahāmati, there are śramaṇas and brāhmaṇas who wish to make manifest the causes and effects of what has no seed and what has a seed, and who hold that phenomena abide through time, and that the aggregates, elements, and sense-fields arise and abide through conditions — or else they say that, once arisen, these then cease. Mahāmati, whether it concerns continuity, or phenomena, or arising, or existence, or nirvāṇa, or the path, or karma, or its fruit, or the truths — their view amounts to a theory of destruction and annihilation. Why is this? Because none of this can be apprehended as actually present, and because their view of the very origin of things is mistaken from the start. Mahāmati, it is like a broken vessel, which can no longer serve as a vessel; or like a scorched seed, which can no longer sprout. Just so, Mahāmati: if the nature of the aggregates, elements, and sense-fields has already ceased, is ceasing now, or will cease in the future — this is merely the false view of one's own mind positing an effect without a cause, and so there is, for them, no orderly, successive arising of anything at all. Mahāmati, if it is further said that consciousness arises from the coming together of three conditions, whether from what has no seed or from what has a seed, then a tortoise ought to grow hair, and sand ought to yield oil. Your own tenet then collapses, contrary to what is certain and settled. The theories of "having a seed" and "having no seed" both carry this same fault, so that all the activities they posit are, in the end, empty and without meaning. Mahāmati, when those tīrthikas speak of arising from the coming together of three conditions, the specific marks of the methods, causes, and effects they posit — whether past, future, or present, whether having a seed or having no seed — have, from the very beginning, been handed down as established fact, turning within the ground of conceptual thought; it is out of the habituated force of their own past errors in view that they make such assertions. Just so, Mahāmati: foolish, ordinary people, harmed by evil views, crooked and intoxicated with delusion, lacking wisdom, falsely claim to speak with the wisdom that knows all things.
The commentary sorts the whole passage into two symmetrical errors before analyzing either one: 無種者，計自然性也；有種者，計此身從微塵生、從世性生 — "no seed" denotes the view that things arise spontaneously, of their own nature; "having a seed" denotes the view that this body arises from atoms, or from a primordial world-nature. Read this way, the broken-vessel and scorched-seed similes are not one example twice but two distinct refutations aimed at each error in turn: 初喻無果，無果則無因也；次喻無因，無因則無果也 — the first simile shows there is no effect, and where there is no effect there can be no cause either; the second shows there is no cause, and where there is no cause there can be no effect either. Denying continuity in the aggregates and sense-fields, the commentary notes, collapses into exactly this trap either way: to say they have "already ceased" is to posit a cause without any effect; to say they "will cease" is to posit an effect without any prior cause — both routes end in the same theory of destruction and annihilation the passage names at the outset.
On the deeper target of "the coming together of three conditions," the commentary is unusually specific about which rival philosophical system stands behind it: 所謂八萬劫前，冥初生覺、覺生性、性生地，次第轉生二十五諦，皆由自己邪見過患熏習餘氣，作如是說也 — referring to [the doctrine that] eighty thousand kalpas ago, the primordial darkness gave rise to intellect, intellect gave rise to individuation, individuation gave rise to the [five] elements, and so on in sequence through the twenty-five principles — all of it spoken out of the residual habituated force of their own past errors in view. This is the Sāṃkhya lineage's own cosmology, named here by a commentator writing in fourteenth-century China with evident familiarity with a rival system from classical India, and the tortoise-hair and sand-oil similes are aimed squarely at it: if a chain of twenty-five successive principles could really generate a cognizing being from mere unconscious "primordial darkness," the commentary implies, one might as well expect a tortoise to grow fur or sand to yield oil — the absurdity of the example is calibrated exactly to the absurdity Zongle and Ruqi take the target doctrine to contain.
Like a Cloud, an Illusion, the Moon in Water
大慧！若復諸餘沙門婆羅門，見離自性、浮雲、火輪揵闥婆城，無生、幻、焰、水月及夢，內外心現，妄想無始虛偽，不離自心。妄想因緣滅盡，離妄想說所說、觀所觀，受用建立身之藏識。於識境界，攝受及攝受者不相應。無所有境界，離生住滅，自心起隨入分別。大慧！彼菩薩不久當得生死涅槃平等，大悲巧方便，無開發方便。大慧！彼一切眾生界，皆悉如幻，不勤因緣，遠離內外境界，心外無所見。次第隨入無相處，次第隨入從地至地三昧境界，解三界如幻，分別觀察，當得如幻三昧。度自心現無所有，得住般若波羅蜜。捨離彼生所作方便金剛喻三摩提，隨入如來身。隨入如如化，神通自在，慈悲方便，具足莊嚴。等入一切佛剎，外道入處，離心意意識。是菩薩漸次轉身，得如來身。大慧！是故欲得如來隨入身者，當遠離陰界入心，因緣所作方便，生住滅妄想虛偽。唯心直進，觀察無始虛偽過妄想習氣，因三有思惟無所有，佛地無生，到自覺聖趣，自心自在，到無開發行。如隨眾色摩尼，隨入眾生微細之心，而以化身隨心量度，諸地漸次相續建立。是故大慧！自悉檀善，應當修學。」
Mahāmati, if there are, on the other hand, other śramaṇas and brāhmaṇas who see that things are apart from own-nature — like a floating cloud, a whirling firebrand, a city of gandharvas, the unborn, an illusion, a mirage, the moon in water, or a dream — and understand that the manifestations of mind, both inner and outer, are false and beginningless, and never apart from one's own mind, then, once the causes and conditions of false thought have utterly ceased, they become free of the false thought bound up with speaking and what is spoken, seeing and what is seen, and free even of the storehouse consciousness that establishes the body of what is received and used. Within the domain of consciousness, the grasped and the grasper no longer correspond to one another; they enter a domain that has nothing at all, apart from arising, abiding, and ceasing, and, arising from their own mind, enter freely into right discrimination. Mahāmati, such a bodhisattva will, before long, attain the equality of birth-and-death and nirvāṇa, great compassion's skillful means, and the skillful means that requires no deliberate exertion. Mahāmati, understanding that the entire realm of sentient beings is, in every case, like an illusion, that bodhisattva, without laboring over causes and conditions, is far removed from every inner and outer object, and sees nothing at all apart from mind. He enters, in due order, the place without any mark; he enters, in due order, the samādhi-domain that proceeds from ground to ground; understanding the three realms to be like an illusion, and discerning and observing them as such, he attains the illusion-like samādhi. He passes beyond his own mind's manifestation of nothingness and comes to abide in the perfection of wisdom. Relinquishing the deliberate means bound up with continued birth, he attains the vajra-like samādhi and enters directly into the Tathāgata's own body. He enters into the transformations of suchness itself, with mastery in the superknowledges, adorned fully with compassion's skillful means. He enters equally into every buddha-land, and even into the domain the tīrthikas enter, while remaining apart from mind, will, and consciousness. Such a bodhisattva, transforming his very body by stages, attains the body of the Tathāgata. Mahāmati, therefore, one who wishes to attain the body the Tathāgata enters directly into should be far removed from the mind bound up with the aggregates, elements, and sense-fields, from the deliberate means bound up with causes and conditions, and from the false and unreal notions of arising, abiding, and ceasing. Advancing directly by mind alone, observing the beginningless faults of falsehood and the habituated force of false thought, and, by contemplating the three realms of existence, finding they have nothing at all — one arrives at the buddha-ground's non-arising, reaches the noble path of self-realization, attains mastery over one's own mind, and reaches the practice that requires no exertion at all. Just as a maṇi-gem takes on whatever color is placed before it, such a one enters freely into the subtlest recesses of every sentient being's mind, and, taking on a transformation-body suited to the measure of that mind, establishes, by stages and in succession, their progress through the bodhisattva grounds. Therefore, Mahāmati, the excellence of one's own understanding of the four siddhāntas should be diligently studied."
The commentary reads the seven similes — cloud, firebrand, gandharva-city, illusion, mirage, water-moon, dream — as together denying every possible account of how a thing could arise, not merely denying that things are solid: 見一切法悉離自生性執，亦離他生、共生、無因生性執，今總略云自性 — seeing that all dharmas are free of the fixed view that they arise from themselves, and equally free of the views that they arise from another, from both together, or from no cause at all; the passage's own summary term, "apart from own-nature," compresses all four denials into one phrase. Freed of this fourfold grasping, the commentary continues, 自心性離，則妄想因緣滅盡 — when one's own mind's nature is thus set free, the causes and conditions of false thought are utterly extinguished — which is why the passage can move, within the same breath, from denying every theory of origination straight to a bodhisattva becoming free even of the storehouse consciousness's own constructive activity: seeing through causation this thoroughly does not stop at refuting rival philosophers, but dissolves the practitioner's own subtlest remaining attachment to a self that receives and uses things.
On the vajra-like samādhi that then carries the bodhisattva into the Tathāgata's own body, the commentary is precise about rank: 等覺菩薩用佛智斷最後微細無明，能斷難斷，故以金剛至堅至利之物喻之 — a bodhisattva at the stage of "equal enlightenment" uses a buddha's own wisdom to sever the very last, subtlest trace of ignorance, cutting what is otherwise nearly impossible to cut, and it is for this reason that the image chosen is vajra, the hardest and sharpest of all substances. This is described as 金剛後心所得之定，從此定轉入佛地 — the samādhi attained at the final moment of this vajra-mind, from which one turns directly into the ground of buddhahood itself — the single hardest transition on the entire path, reserved for its single hardest metaphor. The commentary closes by tying the maṇi-gem simile directly to this same summit: it is not a general image for compassion in the abstract, but a precise description of the buddha-ground's own mode of activity — responding to whatever color, whatever mind, is placed before it, without ever needing to deliberate or exert effort in doing so, which is exactly the "practice that requires no exertion" (無開發行) the passage has just named.
Part 4 Complete
This closes Part 4: the refutation of heterodox causation theories, including the Sāṃkhya lineage's own twenty-five principles named directly by the commentary, and the positive teaching of seeing all dharmas as like an illusion — the insight that carries a bodhisattva through the vajra-like samādhi into the Tathāgata's own body, responsive to every mind like a maṇi-gem taking on whatever color is placed before it. Part 5 turns to the passage this collection's opening page promised: Mahāmati's request to hear of "the ocean-wave storehouse-consciousness domain of the dharma-body," and the Buddha's answer — the four causes by which the eye-consciousness turns, and the great ocean of the ālayavijñāna, its waves rising as the seven consciousnesses never cease.
