13.37

一切種子如暴流者，此一句舉第八識深細之義而不為說，即第一深細不說所以。景師云：阿楞伽云阿陀那識是如來藏者，據賴耶識有一煩惱種故，能藏彼如來法身名如來藏，又賴耶中有彼如來無染種子能藏多果名如來藏。又云八九種種識者，總就諸識，識別有九品，不欲論識有八九種。（基云）水未風擊名曰平流；若遇風濤方成浪起，此識亦，能熏之風未鼓，但只念念平流；若能熏之風鼓時，成種遂如波浪；或種生現，由如波浪，一浪因至一浪生，多浪因，至多浪起也。

Regarding "all seeds [flow] like a torrent": this single line presents the meaning of the eighth consciousness being deep and subtle, on account of which it is not taught; this is the first reason why it is not taught, namely, its depth and subtlety. Master Jing says: "The Laṅkā[vatārasūtra] says that the ādānavijñāna is the tathāgatagarbha because, based on the fact that the ālaya-consciousness possesses a single seed of affliction, it is able to conceal that tathāgata dharmakāya and is thus called tathāgatagarbha; furthermore, within the ālaya there are taintless seeds of that tathāgata capable of containing many fruits, and it is thus called tathāgatagarbha. It also says that there are eight or nine various kinds of consciousnesses, referring generally to all consciousnesses, distinguishing nine grades of consciousness, without intending to argue that consciousness has eight or nine separate kinds." (Ji says:) "When water is not struck by the wind, it is called a calm flow; only when it encounters wind and waves do surges rise up. This consciousness is also like this: when the wind of active perfuming has not stirred, it is merely a calm flow thought-moment by thought-moment; when the wind of active perfuming stirs, it forms seeds and immediately becomes like waves; or, seeds giving rise to actualities is like waves: when the cause of a single wave arrives, a single wave arises; when the causes of many waves arrive, many waves rise up."
