成唯識論演祕 3.689

3.689

有云：界有三義：一者因義，二是性義，三者種也。今依因義以釋界言，疏唯取種，今取現行。與所得種體不異故，說現親生名之為因。現識亦名種子識故，因相唯取現行識故，故下依用但說現依，不說種也。

Some say: 'Element' has three meanings: first, the meaning of cause; second, the meaning of nature; third, seed. Now, in explaining the word 'element' based on the meaning of cause, the Commentary takes only seeds, but I now take active manifestations. Because it is not different in substance from the attained seeds, the active manifestation's directly producing [things] is called 'cause'. Because the actively manifesting consciousness is also called the seed-consciousness, and because the causal characteristic takes only the actively manifesting consciousness, the text below, in explaining its function, speaks only of active support and does not mention seeds.
