The idea given by the most prominent Eastern Philosophy (Vedanta) is that the Absolute should be a non-dual substance that harmonizes all dualities and that it is not afected by any of them.
Creation is only noticed by one's conscience, and so, there are different levels of creation acccording to the state of conscience.
As the Asolute is the Absolute conscience and the collective conscience, all the individual beings that are also part and parcels of that Absolute, should notice and experience these different levels ofcreation.
That philosophic school classifies 5 stages of consciousness, as follows:
1. jagrata or awaken state.
2. sandhya or dreaming state
3. suspti or deep sleep, with no dreams.
4. mugdha or swoomin state.
5. samadhi or supra-consciousnes state.
The idea given by them is that the non-dual substance termed as Brahman should harmonize creation and the different aspects of it with non-creation.
Thus, susupti is taken as the state of non-creation that harmonizes creation. And it can also be experimented by everyone, as well as creations.
