瑜伽師地論略纂 6.128

6.128

現量文有三：一、標；二、釋；三、問答辨。　「已生已等生，若生若起」者，於過去世異熟增上果，名已生；等流果，名已等生，等是相似義故。住現在生，名若者；若住未來生，名若起。

The text on direct perception (pratyakṣa) has three parts: first, the topic; second, the explanation; third, distinguishing by questions and answers. "Already arisen, already arisen equally, arising, or occurring": in the past, a fruition of maturation or an empowering fruit is called "already arisen"; an outflow fruit is called "already arisen equally," because "equal" has the meaning of similarity. What abides in the present arising is called "arising"; what abides in future arising is called "occurring."
