The four steps of the Divine Shakti

The Transcendent Mother thus stands above the Ananda plane. There are then four steps of the Divine Shakti:
(1) The Transcendent Mahashakti who stands above the Ananda plane and who bears the Supreme Divine in her eternal consciousness.
(2) The Mahashakti immanent in the worlds of Sat- Chit-Ananda where all beings live and move in an ineffable completeness.
(3) The Supramental Mahashakti immanent in the worlds of Supermind.
(4) The Cosmic Mahashakti immanent in the lower hemisphere.
