Letters of Sri Aurobindo
Volume I - Part 2
There is always a part of the mind, of the vital, of the body which is or can be influenced by the psychic; they can be called the psychic-mental, the psychic-vital, the psychic-physical. According to the personality or the degree of evolution of each person, 
this part can be small or large, weak or strong, covered up and inactive or prominent and in action. When it acts the movements of the mind, vital or physical accept the psychic motives or aims, partake of the nature of the psychic or follow its aims but with a modification in the manner which belongs to the mind, vital or physical. The psychic-vital seeks after the Divine, but it has a demand in its self-giving, desire, vital eagerness the psychic has not, for the psychic has instead pure self-giving, aspiration, intensity of psychic fire. The psychic-vital is subject to pain and suffering, which there is not in the psychic.
Atma is not the same as psychic – Atma is the self which is one in all, calm, wide, ever at peace, always free. The psychic being is the soul within that experiences life and develops with evolving mind and life and body. The psychic does not suffer like the vital or body, it has not pain or anguish or despair; but it has a psychic sorrow which is different from these things. It has a kind of quiet sweet sadness of yearning which it feels when things go against the Divine, when the obscurity and obstacles are too heavy, when the mind, vital and physical follow after other things, when evil and falsehood and darkness seem to be too strong for the Light. It does not despair, but feels that these things ought not to be and the psychic yearning for it to be otherwise becomes so intense that it is felt as if something akin to sadness.
As for the psychic not being in front, that cannot be brought about all at once; the other parts of the being must be prepared for the change and the veil between must become thinner and thinner. It is for that experiences come and there is the working on the inner mind and vital and physical as well as on the outer nature.
