6. The Divine and the Hostile Powers
Fragment ID: 589
The three stages you speak of are stages not of evolution but of the involution of the Divine in Matter. The Devas and Asuras are not evolved in Matter; for the typal being only a Purusha with its Prakriti is necessary – this Purusha may put out a mental and vital Purusha to represent it and according as it is centred in one or another it belongs to the mental or vital world. That is all.
There is no essential difference anywhere, for all is fundamentally the essential Divine, the difference is in the manifestation. Practically we may say that the Jivatman is one of the Divine Many and dependent on the One; the Atman is the One supporting the Many. The psychic being does not merge in the Jivatman, it becomes united with it so that there is no difference between the eternal being supporting the manifestation from above and the same being supporting the manifestation from within it, because the psychic being has become fully aware of the play of the Divine through it. What is called merging takes place in the Divine Consciousness when the Jivatman feels itself so one with the Divine that there is nothing else.
