大乘百法明門論開宗義決 1.32

1.32

Regarding "and relying on the aggregates and so forth, there is a distinct self": What this school asserts is that among dharmas such as the five aggregates, if spoken of individually, there is no function; but when they are aggregated together, there is a universal characteristic of sovereign agency and function. It is like carts, houses, and the like: if the forest trees are separated individually, their function is absent, but when assembled together, they have real utility. This is just the same.
