Thou dwellest within the five Sheaths (the Annamâyâ, the Prânamâyâ, the Manomâyâ, the Vijñânamâyâ and the Ânandamâyâ sheaths are the five sheaths here referred to). Thou art the Indweller of the Ânanda mâyâ kosa, Thou art of the nature of Puchchha Brahmâ, the end of Brahmâ. Thou art the Deity of all, the Ânanda (bliss) unblown, O Mother! Thou art the Deity of all the Upanisadas.
