成唯識論演祕 3.4

3.4

Explanation: 'Both kinds of seeds' refers to internal and external seeds. 'Coexisting' means not past or future, nor separated, so that they can serve as seeds. Why? Because when the seed exists at that very time, the fruit arises at that same time. 'Constantly accompanying' refers to the ālaya-vijñāna, up to the seeds of external dharmas cultivated for livelihood, up to the abiding of the roots, or up to maturation. 'Determinate' means that these seeds are individually determined; they do not arise all from all, but from the seed of this thing, this very thing is produced. 'Depending on conditions' means that these seeds depend on their own cluster of conditions to be able to produce fruit; they cannot produce everything at all times. If in such a place and at such a time they encounter their own cluster of conditions, then in this place and at this time their own fruit is produced. 'Leading only to their own fruit' means that their own seed leads only to its own fruit; just as the seed of the ālaya-vijñāna can only lead to the arising of the ālaya-vijñāna, and just as rice grain seeds can only lead to the arising of rice grain fruits and the like. As for the rest, the seeds of external dharmas are not mentioned because they are easy to understand. By raising the difficult, the opening statement of the text is illuminated, for it says "all seeds".'
