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.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
