瑜伽師地論略纂 13.18

13.18

論云「如理思、不如理思」，可知。　「或無思慮」，無心定也。　「或謂尋伺」，有心定也。　「在定，不在定」，可知。此意謂此六位之時，境非一種，領受非一，心不並生，意緣此隨一種境。或有聲至，謂不並生，若無第八，起何領受？若有第八，第八領受。雖入定等，無餘五識，覺受仍生。若無第八，此不應起。是此中意也。

The treatise says: "Proper reflection, improper reflection"—this is clear. "Or without reflection"—this is the mindless absorption. "Or possessing vitarka and vicāra"—this is the absorption with mind. "In absorption, not in absorption"—this is clear. The meaning here is that during these six states, the cognitive objects are not of one kind and the experiences are not single; since minds do not arise simultaneously, the mental consciousness takes any one of these objects as its cognitive object. Or if a sound arrives, they claim [consciousnesses] do not arise simultaneously; if there is no eighth, what experience would arise? If there is an eighth, the eighth experiences it. Even though one enters absorption and so on and lacks the remaining five consciousnesses, the experience of awareness still arises. If there is no eighth, this should not arise. This is the meaning here.
