瑜伽論記 1.126

1.126

第二解云，由第八識，得二種子名，一、親因緣，即識中種；二、增上緣，即種持識，依止根本，能生之義，亦名種子。彼論以二緣別故，說現行入俱有依中。此論以能生義故，說現行第八，亦名種子。種子是所執，能依現行，是能執所依，故亦不相違。

The second explanation says: due to the eighth consciousness, two designations of "seed" are obtained: first, the direct cause-condition, which is the seed within consciousness; second, the sovereign condition, which is the consciousness holding the seeds; relying on the fundamental, the meaning of being able to produce is also called seed. Because that treatise differentiates the two conditions, it says the active [consciousness] is included in the simultaneously existing basis. Because of the meaning of being able to produce, this treatise says the active eighth [consciousness] is also called a seed. The seed is that which is grasped, and the active [consciousness] that can serve as support is that which grasps the basis; therefore they also do not contradict each other.
