Sūtra translation
Otherwise, the promissory statement would fail ; and ether mutt be held to have originated, since it is not excluded from all, according to the words (Srutis).
If what is different from Brahman be held to be absolutely eternal (not originated), then the promissory statements such as, “ He created all this,” (Tait. II. 6), would be contradicted. For even ether is not something that is not included in the ‘all’ “ Indeed the Lord alone was at the beginning of this (world) [A.A. 1 1.] Sat only, O gentle one (O thou deserving of Soma) was before this (creation). It was but one without a second [Ch. VI. 2 1]. ‘At the begin- ning of this (world) there was nothing indeed.' [T. B. II. 2. 9].” From these texts, it is clear that Brahman alone is absolutely eternal (not originated).
