13.81

今應立量云：異生所起善等心時必有我見（宗），此是有簡可須思之，是異生故（因），如起餘位我見之時（喻）。此三種業義已成立，於一切時必須恒有，若境業起時必須有四，不然唯前三，了別境業二乘共許，前三業義已成，故於一切時四業可得，於前三業總立量云：異生身中，無染心等現在前時，有前三種業（宗），異生位故（因），如二共所許三種了別現在前時（瑜）。以此義故，四業可知。以理遠立前唯識是。

Now one should formulate the syllogism: 'When an ordinary worldling gives rise to wholesome and other states of mind, they must have the view of self (thesis)—this has a qualification and should be considered—because of being an ordinary worldling (reason), just like at the time of giving rise to the view of self in other states (example).' The meaning of these three kinds of activities having already been established, they must constantly exist at all times. If the activity regarding an object arises, there must be four; otherwise, there are only the former three. The activity of cognizing objects is mutually accepted by the two vehicles, and since the meaning of the former three activities has already been established, therefore at all times the four activities are obtainable. Formulating a general syllogism for the former three activities: 'In the body of an ordinary worldling, when undefiled mind and the like are manifest, the former three kinds of activities exist (thesis), because of the state of being an ordinary worldling (reason), just like when the three kinds of cognition mutually accepted by both are manifest (example).' Through this reasoning, the four activities can be known. Establishing the previous consciousness-only by reason is correct.
