Panchadashi 1.6, 1.7

The awareness during the time of sleep is different than its object, it is not different than the awareness of the dream. So in this manner, in the same day, in all three states of waking etc., in the next day, week, month, year, century or eon, past or future, there is only one awareness. It never is created nor does it perish. This awareness is a self-illumined essence.

The experience of that lack of science in the sleep state should be different than the object called lack of science. But there is no reason why that awareness should be different than the awareness of dream, or any other awareness. In this manner, in one day, in all three states, only one awareness remains. This needs to be understood. The non-differentiation in other periods of time should also be understood.

The object of awareness may keep changing, but there is no change in awareness. Since it is uniform like the flame of a lamp, it is neither created nor destroyed. If we assume that this awareness also is created and destroyed, who will be the witness that knows its creation and destruction? Also, it cannot watch the creation and destruction of itself. There is no other awareness found that can imbibe this creation and destruction. That is why, this awareness is considered beyond birth and death.

This awareness is self-illumined. This awareness which is self-illumined is being perceived, and is illumining the entire world. This is why the entire world is spared from being blind. If this awareness were absent, the world would be blind.
