Sri Aurobindo's Conversations with Pavitra. Part 15. The rejection of Desire

Sri Aurobindo's Conversations with Pavitra. Part 12. Two Parts of the Mind

Sri Aurobindo: In the first analysis, the mind is divided into two parts: one, whose movements are aroused by Nature; the other which shares the nature of the Purusha and remains immobile.
