8.277

述曰：第二復次，解頌答問。於中有三：一、總標；二、別解；三、指例。此初也。今三習氣即《攝論》第三、第四三種熏習。

The Commentary states: In the second "furthermore", it explains the verse to answer the inquiry. Within this there are three parts: first, a general indication; second, separate explanations; third, pointing to examples. This is the first. Now the three vāsanās are precisely the three kinds of perfuming in the third and fourth fascicles of the Mahāyānasaṃgraha.
