That sage who has solely engaged himself in drinking the nectar which is no other than the Brahman, the nectar which is the outcome of incessant mediation, that sage becomes the greatest of ascetics, Paramahansa, and a philosopher free of worldly taint, Avadhuta. By the sight of him, the whole world becomes consecrated. Even an ignorant man who is devoted to his service becomes liberated. - The Upanishads.
