(a) The tendency of modern thought is to recur to the archaic idea of a homogeneous basis for apparently widely different things—heterogeneity developed from homogeneity. Biologists are now searching for their homogeneous protoplasm and Chemists for their protyle, while Science is looking for the force of which electricity, magnetism, heat, and so forth, are the differentiations. The Secret Doctrine carries this idea into the region of metaphysics, and postulates a “One Form of Existence” as the basis and source of all things. But perhaps the phrase, the “One Form of Existence,” is not altogether correct. The Sanskrit word is Prabhavâpyaya, “the place [or rather plane] whence is the origination, and into which is the resolution of all things,” as a commentator says. It is not the “Mother of the World,” as translated by Wilson;(66) for Jagad Yoni, as shown by Fitzedward Hall, is scarcely so much the “Mother of the World,” or the “Womb of the World,” as the “Material Cause of the World.” The Purânic commentators explain it by Kârana, “Cause,” but Esoteric Philosophy, by the _ideal spirit of that cause_. In its secondary stage, it is the Svabhâvat of the Buddhist philosopher, the Eternal Cause and Effect, omnipresent yet abstract, the self‐existent plastic Essence and the Root of all things, viewed in the same dual light as the Vedântin views his Parabrahman and Mûlaprakriti, the one under two aspects. It seems indeed extraordinary to find great scholars speculating on the possibility of the Vedânta, and the Uttara Mîmânsâ especially, having been “evoked by the teachings of the Buddhists”; whereas, on the contrary, it is Buddhism, the teaching of Gautama Buddha, that was “evoked” and entirely upreared on the tenets of the Secret Doctrine, of which a partial sketch is here attempted, and on which, also, the _Upanishads_ are made to rest.(67) According to the teachings of Shrî Shankarâchârya our contention is undeniable.(68) (b) “Dreamless Sleep” is one of the seven states of consciousness known in Oriental Esotericism. In each of these states a different portion of the mind comes into action; or as a Vedântin would express it, the individual is conscious in a different plane of his being. The term “Dreamless Sleep,” in this case, is applied allegorically to the Universe to express a condition somewhat analogous to that state of consciousness in man, which, not being remembered in a waking state, seems a blank, just as the sleep of the mesmerized subject seems to him an unconscious blank when he returns to his normal condition, although he has been talking and acting as a conscious individual would. 9. BUT WHERE WAS DANGMA WHEN THE ÂLAYA OF THE UNIVERSE(69) WAS IN PARAMÂRTHA (_a_),(70) AND THE GREAT WHEEL WAS ANUPÂDAKA (_b_)?
