In the state called dreamless sleep the manifest human body which, of course, is the door of dreams, disappears in the mind. Possessing the body the mind enters the Soul which is unmanifest and upon which all existent and non-existent things depend, and becomes a wakeful witness with certainly of apprehension. Thus living in pure Consciousness which is the soul of all things, it is considered by the learned as transcending both Consciousness and all things in the universe.
मनस्यन्तर्हितं द्वारं देहमास्थाय मानुषम्। यद् यत् सदसदव्यक्तं स्वपित्यस्मिन्निदर्शनम्। सर्वभूतात्मभूतस्थं तमध्यात्मगुणं विदुः॥
