17. Should it be said that on account of the connected meaning (of the whole passage) (the highest Self cannot be meant); (we reply that) it is so, on account of the assertion.
We now have to refute the objection, made above by the pûrvapakshin, that the highest Self cannot be meant 'on account of the connected meaning of the passage.'--The Sûtrakâra remarks, 'It is so, on account of the assertion.' That means: It is appropriate to understand the passage as referring to the highest Self, because thus the assertion that the Self, previously to the creation, was one only, gives a fully satisfactory sense, while on the other interpretation it would be far from doing so. The creation of the worlds recorded in the Aitareyaka we connect with the creation of the elements recorded in other Vedic texts, in that way that we understand the worlds to have been created subsequently to the elements; just as we showed above (II, 4, 1) that the passage, 'It sent forth fire,' must be understood to say that the creation of fire followed on the creation of ether
The two preceding Sûtras may also be explained with reference to some other Vedic passages. We read in the Vâgasaneyaka (Bri. Up. IV, 3, 7), 'Who is that Self?--He who is within the heart, surrounded by the prânas, consisting of knowledge, the person of light.' Of the Self here first mentioned the text goes on to show that it is free from all contact and thus proves it to have Brahman
210:1 I.e. the definite statement about the Self in the concluding passage may be used for defining the sense of the indefinite initial statement about that which is. 'That which is' comprises the Self as well as the Not-Self.
