All Life Is Yoga: The Soul and How to Find It

"The soul, the psychic being, is in direct touch with the divine Truth, but it is hidden in man by the mind, the vital being and the physical nature (manas, prana, anna of the Taittiriya Upanishad). One may practise Yoga and get illuminations in the mind and the reason; one may conquer power and luxuriate in all kinds of experiences in the vital; one may establish even surprising physical siddhis; but if the true soul-power behind does not manifest, if the psychic nature does not come into the front, nothing genuine has been done. In this Yoga, the psychic being is that which opens the rest of the nature to the true supramental light and finally to the supreme Ananda." – Sri Aurobindo

"In truth, the only thing that is truly tragic is not to become conscious of one’s soul, the psychic being, and not to be entirely guided by it in one’s life.

To die before having found one’s soul and lived according to its law, that is the true failure." – The Mother
