成唯識論述記 8.199

8.199

述曰：若後以前念為所緣緣，自身八識品相望中，前七於第八亦容有所緣緣，以前七識皆能熏成彼第八品相、見種故。謂前五識為能熏，成彼第八相分色等相分種故，是第八見分所緣緣，第七識為能熏，成彼第八見分種故，是自證分所緣緣。自證等種，生自證等，隨應亦爾。第六識若緣第八見相而熏種，即雙熏彼二分種子；若緣虛空、心、心所等以為相分，亦熏彼生空等相種也，非是能熏生彼第八現行相、見分種也，第八不緣虛空等故，此七識中望彼第八相、見分等應作四句，其第六識具後二句，如理可知。即是二義與前師別，六望七等准此應知。

The Commentary states: If the succeeding takes the preceding moment as an objective condition, then among the eight classes of consciousness of one's own stream viewed in relation to one another, the preceding seven may also serve as objective conditions for the eighth, because the preceding seven consciousnesses can all perfuse and produce the seeds of the eighth's nimittabhāga and darśanabhāga. That is to say, the preceding five consciousnesses serve as the perfuming agents that produce the seeds of the eighth's nimittabhāga (such as form), and are thus objective conditions for the eighth's darśanabhāga; the seventh consciousness serves as the perfuming agent that produces the seeds of the eighth's darśanabhāga, and is thus an objective condition for its svasaṃvittibhāga. Seeds of the svasaṃvittibhāga and so forth generate the svasaṃvittibhāga and so forth, and this should likewise be understood accordingly. If the sixth consciousness cognizes the darśanabhāga and nimittabhāga of the eighth and perfuses seeds, it perfuses seeds of both divisions; if it cognizes empty space, citta, caitasikas, and so forth as its nimittabhāga, it also perfuses seeds that produce the marks of empty space and so forth, but is not that which perfuses seeds that produce the active nimittabhāga and darśanabhāga of that eighth consciousness, because the eighth does not cognize empty space and so forth. Among these seven consciousnesses viewed in relation to the eighth's nimittabhāga and darśanabhāga, a fourfold proposition (catuṣkoṭi) should be constructed; the sixth consciousness possesses the latter two propositions, which can be understood through reason. These are two points of difference from the previous master; the sixth viewed in relation to the seventh, and so forth, should be known by analogy with this.
