Thus Even In Deep Sleep, Though There Is No Concrete Object Of Cognition

 - "The cognition of darkness in sleep becomes recollection of him who has woke up after sleeping. That (recollection) has for its content what had been cognised before.

- Therefore darkness was cognised then (while sleeping)." there is the cognition of the absence of any such object, in other words, cognition of darkness

- As there is such cognition, it is clear that the cognising entity does subsist even in sleep and that therefore there is no break in the continuity of its existence

- It is distinct and Independent of any object of cognition. It follows therefore that the cognising entity is quite same throughout the day, though the objects of cognition

- may vary, the external world in the waking state, the dream-created world while dreaming and mere darkness in deep sleep

- The identity of the cognising entity is never lost. When the sleeper of the night wakes up the next morning, he is quite conscious that it was he that slept

- that it was he that dreamt and that it was he that was awake and experienced the previous day. So the continuity is kept up without any break

- "That cognition (had during sleep) is different from the object (then darkness) but is not different from cognition itself, just as the cognition during the dream state (is not different from the cognition in the waking state)
