The essence of Vedanta is that there is but one Being and that every soul is that Being in full, not a part of that Being.
Swami VivekanandaSo long as there is desire or want, it is a sure sign that there is imperfection. A perfect, free being cannot have any desire.
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
