Adhikaraṇa 1: The section entitled "The
ether". (Sūtras 1-6)
PRIMA FACIE VIEW (Sūtra 1)
SŪTRA 1
"THE ETHER (DOES) NOT (ORIGINATE), ON ACCOUNT OF NON-
MENTION IN SCRIPTURE."
Vedānta-pārijāta-saurabha
That there is no contradiction in our own view has been proved by
means of the views of the opponents. Now, it is being proved that
there is no mutual non-contradiction among the scriptural texts.
"The ether" does "not" originate. Why? Because in the
Chāndogya its origin is not mentioned.
Vedānta-kaustubha
Thus, having demonstrated that the views of the opponents are
based on a mere semblance of (and not real) reason, now with a view
to generating intense reverence for Brahman, the cause of the world,
on the part of those who are desirous of salvation, (the author) is
demonstrating the origin of the ether and the rest, His effects, as well
as the mutual consistency among the scriptural texts (about them).
On the doubt, viz. whether the ether originates or not, the prima
facie view is as follows: "The ether" does not originate. Why?
"On account of non-mention in Scripture." Thus in the Chāndogya,
the creation of three only—viz. light, water and food, without the
ether and the air, is mentioned in the section concerned about creation
in the passage beginning: 'He created that Light' (Chānd. 6.2.3).
