PLANES

Sat, Chit, Ananda, Supermind, Mind, Life, Matter are the seven planes described in the Veda — but in this yoga one sees many levels of consciousness...
Mind has its own realms and life has its own realms just as matter has. In the mental realms life and substance are entirely subordinated to Mind and obey its dictates. Here on earth there is the evolution with matter as the starting-point, life as the medium, mind emerging from it. There are many grades, realms, combination in the cosmos — there are even many universes. Ours is only one of many.

...we must understand what we mean by planes of consciousness, planes of existence. We mean a general settled poise or world of relations between Purusha and Prakriti, between the Soul and Nature.. For anything that we can call world is and can be nothing else than the working out of a general relation which an universal existence has created or established between itself, or let us say its eternal fact or potentiality and the powers of its becoming. That existence in its elations with and its experience of the becoming is what we call soul or Purusha, individual soul in the individual, universal soul in the cosmos; the principle and the powers of the becoming are what we call Nature or Prakriti.

A hidden Bliss is at the root of things.
A mute Delight regards Time's countless works:
To house God's joy in things Space gave wide room,
To house God's joy in self our souls were born.
