SAT CHIT ANANDA

Sat, Chit, Ananda, Supermind, Mind, Life, Matter are the seven planes described in the Veda...
If you speak of the upper hemisphere as the supernal, there are three, Sat plane, Chit plane and Ananda plane. The supermind could be added as a fourth, as it draws upon the other three and belongs to the upper hemisphere.

In fact in the Reality there is no separateness, the three aspects are so fused into each other, so inseparably one that they are a single undivided reality.

The upper hemisphere contains the Divine existence-consciousness-bliss, with the supermind as its means of self-formulation.

If supermind were to start here from the beginning as the direct creative Power, a world of the kind we see now would be impossible; it would have been full of the divine Light from the beginning, there would be no involution in the inconscience of Matter, consequently no gradual striving evolution of consciousness in Matter. A line is therefore drawn between the higher half of the universe of consciousness, parãrdha, and the lower half, aparãrdha. The higher half is constituted of Sat, Chit, Ananda, Mahas (the supramental) — the lower half of mind, life, Matter. This line is the intermediary overmind which, though luminous itself, keeps from us the full indivisible supramental Light, depends on it indeed, but in receiving it, divides, distributes, breaks it up into separated aspects, powers, multiplicities of all kinds, each of which it is possible by a further diminution of consciousness, such as we reach in Mind, to regard as the sole or the chief Truth and all the rest as subordinate or contradictory to it.

The worlds where all beings live and move in ineffable completeness and unalterable oneness, because the Mother carries them safe in her arms forever. There will and knowledge and sensation and all the rest of our faculties, powers, modes of experience are not merely harmonious, concomitant, unified, but are one being of consciousness and power of consciousness.

The soul that wholly gives itself to Him, God also gives himself altogether. Only the one who offers his whole nature, finds the Self. Only the one who can give everything, enjoys the Divine All everywhere. Only a supreme self-abandonment attains to the Supreme. Only the sublimation by sacrifice of all that we are, can enable us to embody the Highest and live here in the immanent consciousness of the transcendent Spirit.

There is a consciousness mind cannot touch,
Its speech cannot utter nor its thought reveal.
It has no home on earth, no centre in man,
Yet is the source of all things thought and done.
