04. The Triple Transformation: Psychic – Spiritual – Supramental
To speak of “receiving power from the supramental when we are not conscious” is strange. When one is not conscious, one can still receive a higher force, the Divine Shakti works often 
from behind the veil, otherwise in the ignorant and unconscious condition of the human being she would not be able to work at all. But the nature of the force or action is modified to suit the condition of the sadhak. One must develop a very full consciousness before one can receive anything from the direct supramental Power and one must be very advanced in consciousness even to receive something of it modified through the overmind or other intermediate region.
