The distinctions of the waking state, dream state, and sleep state (viswa, taijasa, and prajna) are but appearances imposed on the Atma; that is to say, the Atma continues the same, unaffected by the waking, dreaming, and deep- sleep stages of man’s existence. This Atma and the Atma that one refers to as “I” are basically the same. The “I” or the Atma swims like a fish in the river, paying no regard to this bank or that, though the waters are limited and guided by them.
In deep sleep, all the impulses (vasanas) are suspended; though they still persist, they are not manifest or active. In the dream state, one follows impulses and wins satisfaction in the process.
All the manifold pulls and attractions of the sensory world, which impel one toward the surrounding objects, are born during the waking and dream states. The mind is full of agitations, and these are the fertile fields where the impulses grow, multiply, and strike root. As a matter of fact, it is the agitating mind that causes creation (Srishti) and that is behind all creation.
