五十七說：依止色故名寐於窟，彼說有色界識非未來識，此說通三界識三世別識，以釋頌文，理不相違，遠行者，說過去識，獨行無身二義說現在識，寐於窟者說未來識，即三世四義識名為四相，非去來世而無獨行及無身義，現用可知，從增說現。

Fascicle 57 states: Because it relies on matter, it is called 'sleeping in a cave.' That speaks of consciousness of the form realm, not future consciousness. This speaks broadly of consciousness of the three realms and distinct consciousnesses of the three periods of time to explain the verse, so the principles are not contradictory. 'Far-faring' speaks of past consciousness; the two meanings of 'faring alone' and 'bodiless' speak of present consciousness; and 'sleeping in a cave' speaks of future consciousness. These four meanings of consciousness in the three periods of time are called the 'four marks.' It is not that past and future consciousness lack the meanings of faring alone and bodilessness; since the present functions can be known, it speaks of the present from the standpoint of prominence.
