That Ether is an originated thing follows from other clauses also in the
Chândogya: 'Being only this was in the beginning, one without a second'
affirms the oneness of everything before creation, and 'In that all this
has its Self implies that everything is an effect of, and hence non-
different from, Brahman.--Nor does the statement as to the creation of
fire, 'it sent forth fire,' exclude the creation of Ether. For the first
place which there is assigned to fire rests only thereon that no mention
is made of the creation of Ether, and this has no force to negative the
creation of Ether as positively stated in other texts.
7. But the division (origination) extends over all effects; as in
ordinary life.
The 'but' has the sense of 'and.' As the clause 'In that all this has
its Self' and similar ones directly state that Ether also is a creation
of Brahman, the division, i.e. the origination of Ether from Brahman, is
implicitly declared thereby. As in ordinary life. When in ordinary life
somebody has said 'all these men are the sons of Devadatta,' it is known
that any particulars which may afterwards be given about the descent of
some of them are meant to apply to all.--In accordance with this our
conclusion we interpret the text 'Air and Ether, this is the Immortal,'
as asserting only that air and Ether continue to exist for a long time,
as the Devas do.
