Just as the body has its progress and decadence, so also has the mind, and, therefore, the mind is not the soul, because the soul can neither decay nor degenerate.
Swami VivekanandaDo not go for glass beads leaving the mine of diamonds. This life is a great chance. What, seekest thou the pleasures of the world? He is the fountain of all bliss. See for the highest, aim at that highest, and you shall reach the highest.
Swami VivekanandaPrana, according to the Vedanta, is the principle of life. It is like ether, an omnipresent principle; and all motion, either in the body or anywhere else, is the work of this Prana. It is greater than Akasha, and through it everything lives. Prana is in the mother, in the father, in the sister, in the teacher, Prana is the knower.
Swami Vivekananda
