In the inconscient plane there is no light at all; but the subconscious plane also does not care for light. In the subconscious plane the undivine realities or qualities that do not want to progress come forward whenever they get an opportunity and try to fight against the qualities that are trying to invoke Light from Above. But it is not as difficult to bring light into the subconscious plane as it is to bring light into the inconscient plane. The subconscious plane is better than the inconscient plane, but eventually both these planes have to be conquered and perfected.
Light has to enter into all planes of our being, for only then can we be totally perfect. But it is not advisable for the seeker to enter into either plane in the beginning or middle of his journey, for there he will encounter powerful forces of darkness. Only when one is on the verge of illumination or when one has actually received some illumination is it advisable for him to enter into the subconscious plane to try to illumine it.From:Sri Chinmoy,Flame-Waves, part 4, Agni Press, 1975
