成唯識論述記 1.614

1.614

述曰：此下第三子段，合破勝論、順世二師。謂彼救言：前言果色等於因量，誰謂所生一色之果唯與一个極微量等？今云等者，等如二个父母極微，遍在二因之中。因既有二，果等於彼，故可名麁。

The Commentary states: This is the third sub-section below, jointly refuting the two teachers, the Vaiśeṣika and Lokāyata. That is, they defend their view by saying: When we previously said that the material effect is equal to the size of its cause, who said that one produced material effect is equal in size only to a single atom? What we now call 'equal' means equal to two parent atoms, pervading both causes. Since there are two causes and the effect is equal to them, it can be called coarse.
