應立量云：入無心定等位眼等識根及外器等便應斷絕（宗），以無識故（因），如所滅識（喻）。又緣涅槃等境時諸眼根等必應斷絕（宗），自能緣體無有故（因），猶如未生緣眼等識，此即成立初二種業是有，次成第三業，二乘唯云有了我之業不言一切時起了我。

One should formulate the syllogism: 'In states such as entering mindless concentration, the eye and other conscious faculties as well as the external receptacle and the like should be cut off (thesis), because there is no consciousness (reason), just like consciousness that has ceased (example).' Furthermore: 'When taking nirvāṇa and other such objects as intentional objects, the various eye faculties and the like must necessarily be cut off (thesis), because their own cognizing substance does not exist (reason), just like the yet-to-arise consciousness that takes the eye and other [faculties] as its object (example).' This establishes that the first two kinds of activities exist. Next, establishing the third activity: the two vehicles only say that there is an activity of cognizing a self, but do not say that cognizing a self arises at all times.
