Theosophy
In occultism, akasha it is also defined as the other of the two worlds, the world through which the mwitch or magician walks through being realted to outer space, inner space, life force and the un-manifest.
In short, our Deity is the eternal, incessantly evolving, not creating, builder of the universe; that universe itself unfolding out of its own essence, not being made. It is a sphere, without circumference, in its symbolism, which has but one ever-acting attribute embracing all other existing or thinkable attributes-itself. It is the one law, giving the impulse to manifested, eternal, and immutable laws, within that never-manifesting, because absolute law, which in its manifesting periods is The ever-Becoming.
The Buddhists, on the other hand, deny either subjective or objective reality even to that one Self-Existence. Buddha declares that there is neither Creator nor an ABSOLUTE Being. Buddhist rationalism was ever too alive to the insuperable difficulty of admitting one absolute consciousness, as in the words of Flint - "wherever there is consciousness there is relation, and wherever there is relation there is dualism." The ONE LIFE is either "MUKTA" (absolute and unconditioned) and can have no relation to anything nor to any one; or it is "BADDHA" (bound an conditioned), and then it cannot be called the ABSOLUTE; the limitation, moreover, necessitating another deity as powerful as the first to account for all the evil in this world. Hence, the Arahat secret doctrine on cosmogony admits but of one absolute, indestructible, eternal, and uncreated UNCONSCIOUSNESS (so to translate), of an element (the word is used for want of a better term) absolutely independent of everything else in the universe; a something ever present or ubiquitous, a Presence which ever was, is, and will be, whether there is a God, gods or none; whether there is a universe or no universe; existing during the eternal cycles of Maha Yugas, during the Pralayas as during the periods of Manvantara: and this is SPACE, the field for the operation of the eternal Forces and natural Law, the basis (as our correspondent rightly calls it) upon which take place the eternal intercorrelations of Akasa-Prakriti, guided by the unconscious regular pulsations of Sakti - the breath or power of a conscious deity, the theists would say - the eternal energy of an eternal, unconscious Law, say the Buddhists. Space then, or Fan, Bar-nang (Maha-Sunyata) or, as it is called by Lao-Tze, the "Emptiness" is the nature of the Buddhist Absolute.
