The Upanishads - Mandhata Global

5
We approve the ajati (non-creation) thus established by
them. We have no quarrel with them. Now hear from us
about Ultimate Reality, which is free from all
disputations.
6-8
The disputants assert that the unborn entity (Atman)
becomes born. How can one expect that an entity that is
birthless and immortal should become mortal? The
immortal cannot become mortal, nor can the mortal
become immortal. For it is never possible for a thing to
change its nature. How can one who believes that an
entity by nature immortal becomes mortal, maintain that
the immortal, after passing through change, retains its
changeless nature?
9
By the prakriti, or nature, of a thing is understood that
which, when acquired, becomes the essential part of the
thing, that which is its characteristic quality, that which
is its inalienable nature from its very birth, that which is
not extraneous to it and that which never ceases to be
itself.
10
All the jivas are, by their very nature, free from senility
