A great poem in World Literature, Dakshinamurti Stotra reveals the Poet and the Mystic in Sri Sankaracarya in unison at the highest altitude of his being.
Learning and wisdom are superfluities, the surface glitter merely, but it is the heart that is the seat of all power. It is not in the brain but in the heart that the Atman, possessed of knowledge, power, and activity, has its seat.
-Swami Vivekananda
