成唯識論演祕 6.382

6.382

略為二釋：一、因果同性名為一法，一法因果是實等流，非餘異性是等流也，縱言等流假說之耳；二、唯此報業相似一法假說等流，非自餘法亦皆假說為等流也，不相似故。《疏》舉殺生一業因果，顯餘善惡業報皆是假等流也；除斯以還，不可假說。二解任取。

There are briefly two interpretations: First, when cause and result share the same moral nature, it is called a single phenomenon; the cause and result of a single phenomenon are true equal outflow (niṣyanda), whereas other different natures are not equal outflow; even if called equal outflow, it is merely a metaphorical expression. Second, only this single phenomenon of retribution-karma bearing similarity is metaphorically called equal outflow, while other phenomena are not all metaphorically called equal outflow, because they lack similarity. The Commentary adduces the single karma of killing and its result to show that other karmic retributions of wholesome and evil are all metaphorical equal outflows; outside of this, it cannot be spoken of metaphorically. Either of the two explanations may be adopted.
