Series 2, Chapter 15 pg 437, Para 2: The Kshara spirit visible to us as all natural existence and the totality of all existences moves and acts pervadingly in the immobile and eternal Akshara. This mobile Power of Self acts in that fundamental stability of Self, as the second principle of material Nature, Vayu, with its contactual force of aggregation and separation, attraction and repulsion, supporting the formative force of the fiery (radiant, gaseous and electric) and other elemental movements, ranges pervadingly in the subtly massive stability of ether. This Akshara is the self higher than the buddhi — it exceeds even that highest subjective principle of Nature in our being, the liberating intelligence, through which man returning beyond his restless mobile mental to his calm eternal spiritual self is at last free from the persistence of birth and the long chain of action, of Karma. This self in its highest status, param dhama, is an unmanifest beyond even the unmanifest principle of the original cosmic Prakriti, Avyakta, and, if the soul turns to this Immutable, the hold of cosmos and Nature falls away from it and it passes beyond birth to an unchanging eternal existence. These two then are the two spirits we see in the world; one emerges in front in its action, the other remains behind it steadfast in that perpetual silence from which the action comes and in which all actions cease and disappear into timeless being, Nirvana.
