The Icchantika, and the Three Own-Natures

The commentators are precise that "icchantika" does not name a single fixed condition, and that reading the term as though it did is the very confusion Mahāmati's question is meant to dispel: "非一闡提者，非定是極惡，若定是極惡，則永無轉惡為善得解脫時也。然闡提現行雖惡，性不斷善，若能照性亦得成佛" — "'is, in truth, no icchantika' means he is not necessarily one who is utterly evil; for if he were necessarily utterly evil, there would never be any time at which evil could be turned to good and liberation attained. But though an icchantika's present conduct is evil, his [underlying] nature has not severed goodness — should he come to illuminate that nature, he too can attain buddhahood." This single sentence is the doctrinal root of a controversy that would consume Chinese Buddhism for over a century after this sūtra's translation: whether the icchantika — traditionally read as permanently barred from buddhahood — nonetheless retains buddha-nature and can, in time, awaken. The commentators, writing in the fourteenth century with that controversy long settled in favor of universal buddha-nature, read this line as having answered the question from the very beginning.

On why the bodhisattva "icchantika" of the second kind bears the same name as a being severed from goodness, the commentators locate the shared vocabulary precisely: "菩薩了惡即善，無善可修，趣同闡提，捨一切善及不入涅槃故也" — "the bodhisattva has realized that evil is itself none other than goodness, so that there is, in a sense, no [further, separate] goodness left to cultivate — his destination resembles the icchantika's own, in that he too, in a manner of speaking, 'severs all goodness' and 'does not enter nirvāṇa.'" The resemblance is verbal, not substantive: one icchantika has nothing further to attain because he has refused the path entirely; the other has nothing further to attain because his vow keeps him, by his own choice, permanently at the threshold on every other being's behalf. The commentators' closing point sharpens the distinction the sūtra itself draws only implicitly: "一切眾生即涅槃相，不可復滅" — "every sentient being is, in truth, already the very mark of nirvāṇa, which cannot be extinguished any further" — the bodhisattva's vow is not deferral of an achievement but recognition that the achievement, for every being, was never actually missing.

The commentators fold the three own-natures directly back into the five dharmas named at this fascicle's opening, and are explicit that the two schemes are not independent teachings but the same structure viewed at different resolutions: "名相即緣起自性，覺想即妄想自性，正智如如即成自性，此攝五法為三自性，故知五法、三自性特開合異耳" — "'name and mark' is precisely the dependent own-nature; 'awareness and what it conceives of' is precisely the imagined own-nature; 'true wisdom and suchness' is precisely the perfected own-nature — this gathers the five dharmas into the three own-natures, and one should therefore understand that the five dharmas and the three own-natures differ only in being opened out or drawn together, not in what they actually name." Name, mark, false discrimination, right knowledge, and suchness — the very fivefold list glossed in Part 1's opening reading note — turn out to collapse into exactly these three, with "false discrimination" split across the imagined nature's two sub-marks and "right knowledge" and "suchness" fused into the single perfected nature.

On why the dependent own-nature is described as itself giving rise to the imagined own-nature's two marks, rather than the two being independent errors, the commentators trace the sequence directly: dependent origination first "顯現事相相" (displays itself as the mark of an actual matter) — a genuinely arising, conditioned event — and only then does attachment arise twice over: once to the mere name given to it, and once to the "own mark and shared mark" now taken as real properties of a real thing. The dependent own-nature is not itself the error; it is the raw material false thought seizes upon twice in succession. This is also, on the commentators' reading, why the perfected own-nature is named "the mind of the tathāgatagarbha" (如來藏心) here for the first time in this fascicle — not a fourth, separate reality standing apart from the other two natures, but precisely the dependent own-nature seen free of both layers of attachment the imagined own-nature adds on top of it.
