The text, 'All these beings spring from ether only' (Ch. Up. I, 9, 1), declares that the whole world originates from ether only, and from this it follows that ether is none other than the general cause of the world, i.e. Brahman. This non-difference of Brahman from the empirically known ether also gives a satisfactory sense to texts such as the following: 'If this ether were not bliss' (Taitt. Up. II, 7, 1); 'Ether, indeed, is the evolver of names and forms' (Ch. Up. VIII, 14, 1, and so on).--It thus appears that Brahman is none other than the well- known elemental ether. This primâ facie view is set aside by the Sûtra. The word 'ether' in the text under discussion denotes the highest Self with its previously established characteristics--which is something quite different from the non-sentient elemental ether. For the qualities which the passage attributes to ether, viz. its being the one cause of the entire world, its being greater than all, and the rest of all, clearly indicate the highest Self. The non-intelligent elemental ether cannot be called the cause of all, since intelligent beings clearly cannot be its effects; nor can it be called the 'rest' of intelligent beings, for non-sentient things are evil and antagonistic to the true aim of man; nor can it be called 'greater' than all, for it is impossible that a non-sentient element should possess all excellent qualities whatever and thus be absolutely superior to everything else.--Nor is the Pûrvapakshin right when maintaining that, as the word 'ether' satisfies the demand for a special cause of the world, all other texts are to be interpreted in accordance herewith. The words, 'All these beings indeed spring from the ether only,' merely give expression to something generally known, and statements of this nature presuppose other means of knowledge to prove them. Now these other means required are, in our case, supplied by such texts as 'Being only was this in the beginning,' and these, as we have shown, establish the existence of Brahman. To Brahman thus established, the text mentioning the ether merely refers as to something well known. Brahman may suitably be called 'ether' (âkâsa), because being of the nature of light it shines (âkâsate) itself, and makes other things shine forth (âkâsayati). Moreover, the word 'ether' is indeed capable of conveying the idea of a special being (as cause), but as it denotes a special non-intelligent thing which cannot be admitted as the cause of the intelligent part of the world we must deny all authoritativeness to the attempt to tamper, in the interest of that one word, with the sense of other texts which have the power of giving instruction as to an entirely new thing (viz. Brahman), distinguished by the possession of omniscience, the power of realising its purposes and similar attributes, which we ascertain from certain complementary texts-such as 'it thought, may I be many, may I grow forth,' and 'it desired, may I be many, may I
