That within us which seeks to know and to progress is not the mind but something behind it which makes use of it.
Sri AurobindoThe psychic being and the mental being, Manomaya Purusha, are not the same. The psychic being is behind the mind, it is what the Westerners call the soul. It takes interest in the movements of the mind and the vital only when there is a harmony between these movements and the truth above. The knowledge of the psychic being is deeper.
