like the phases of the moon, there are three states of reflected consciousness. waking is full. dreaming is half. deep sleep is new. they call the sun the fourth but it's not a state. it's the one nondual consciousness.
As an ocean of immortality, I cannot be destroyed by the birth of imaginary waves.
As a crystal mountain, I cannot be colored by the dream of fleeting evening clouds.
~Advaita Makaranda 21
The one who sleeps doesn’t know sleep. The one who doesn't sleep neither wakes nor dreams.
I am the witness of waking, dreaming, and deep sleep, and thus beyond those states.
~Advaita Makaranda 11
A Nondual Creed
1. Consciousness is not a product of the body-mind.
2. Consciousness is the ground upon which the body-mind is superimposed.
3. Consciousness is the noumenal absolute called Brahman.
I am the seer, pure and unchanging.
By my very nature, there aren't any objects to me.
Before and behind, above and below, everywhere is
the all-pervading reality, unborn and abiding as the Self.
~Shankara, Upadesa Saharsi V10.2
