成唯識論述記 8.183

8.183

述曰：此文總也。不簡自、他識等相望容作三緣，現望於現，非親辨體，無因緣故。

The Commentary states: This text is the general [explanation]. Without distinguishing one's own or another's consciousness and so forth, when viewed in relation to one another they are admissible to act as three conditions; because actual states viewed in relation to actual states do not directly produce the entity, there is no causal condition.
