Sri Aurobindo next describes the involution of consciousness from pure Spirit at the summit, to Matter as the last stage, which provides the foundation for the subsequent evolution of consciousness which we experience here.
“In the descent into involution there can be distinguished seven principles of manifested being, seven gradations of the manifesting Consciousness of which we can get a perception or a concrete realisation of their presence and immanence here or a reflected experience. The first three are the original and fundamental principles and they form universal states of consciousness to which we can rise; when we do so, we can become aware of supreme planes or levels of fundamental manifestation or self-formulation of the spiritual reality in which is put in front the unity of the Divine Existence, the power of the Divine Consciousness, the bliss of the Divine Delight of existence,–not concealed or disguised as here, for we can possess them in their full independent reality. A fourth principle of supramental Truth-Consciousness is associated with them; manifesting unity in infinite multiplicity, it is the characteristic power of self-determination of the Infinite. This quadruple power of the supreme existence, consciousness and delight constitutes an upper hemisphere of manifestation based on the Spirit’s eternal self-knowledge. If we enter into these principles or into any plane of being in which there is the pure presence of the Reality, we find in them a complete freedom and knowledge. The other three powers and planes of being, of which we are even at present aware, form a lower hemisphere of the manifestation, a hemisphere of Mind, Life and Matter. These are in themselves powers of the superior principles; but wherever they manifest in a separation from their spiritual sources, they undergo as a result a phenomenal lapse into a divided in place of the true undivided existence: this lapse, this separation creates a state of limited knowledge exclusively concentrated on its own limited world-order and oblivious of all that is behind it and of the underlying unity, a state therefore of cosmic and individual Ignorance.”
