瑜伽論記 23.254

23.254

長行中，初解唯緣，景師云：謂業煩惱，及自種子是所引受因緣，六觸處望受，唯為所依增上緣。下舉喻顯，如心所起功用所引諸取受業，手唯能作助取受緣者，如欲執取草木，心為取因，手為助取緣。達師云：今大乘法，由心發作生活正因，其中手能助作緣，亦作生活。此中由心所發業者，喻本識中種子因緣，言手者，喻觸為受起之緣，則是現緣。

In the prose, first, explaining 'condition alone': Master Jing says: Karma, defilements, and their own seeds are the causes and conditions for the feelings that are induced; relative to feeling, the six contact-bases merely serve as the supporting predominant condition. Below, an analogy is adduced to clarify: just as with karma of grasping and receiving induced by the effort initiated by the mind, the hand can only serve as an auxiliary condition for grasping and receiving. For example, if one wishes to grasp grass and wood, the mind is the cause of grasping, and the hand is the auxiliary condition for grasping. Master Da says: In the Great Vehicle's teaching now, the mind initiates and performs the primary cause of livelihood, within which the hand can assist as an active condition, also creating livelihood. Here, the karma initiated by the mind is an analogy for the causes and conditions of the seeds in the fundamental consciousness; the word 'hand' is an analogy for contact being the condition for the arising of feeling, which is the present condition.
