is to be meditated on is Brahman as possessing qualities. (The text from
the Ke. Up. then explains itself as follows:--) We are informed by the
passage 'from whence speech together with mind turns away, being unable
to reach it', that the infinite Brahman with its unlimited excellences
cannot be defined either by mind or speech as being so or so much, and
from this we conclude the Kena text to mean that Brahman is not thought
and not understood by those who understand it to be of a definitely
limited nature; Brahman in truth being unlimited. If the text did not
mean this, it would be self-contradictory, parts of it saying that
Brahman is _not_ thought and _not_ understood, and other parts, that it
_is_ thought and _is_ understood.

Now as regards the assertion that the text 'Thou mayest not see the seer
of seeing; thou mayest not think the thinker of thinking' (Bri. Up. III,
5, 2), denies the existence of a seeing and thinking subject different
from mere seeing and thinking--This view is refuted by the following
interpretation. The text addresses itself to a person who has formed the
erroneous opinion that the quality of consciousness or knowledge does
not constitute the essential nature of the knower, but belongs to it
only as an adventitious attribute, and tells him 'Do not view or think
the Self to be such, but consider the seeing and thinking Self to have
seeing and thinking for its essential nature.'--Or else this text may
mean that the embodied Self which is the seer of seeing and the thinker
of thinking should be set aside, and that only the highest Self--the
inner Self of all beings--should be meditated upon.--Otherwise a
conflict would arise with texts declaring the knowership of the Self,
such as 'whereby should he know the knower?' (Bri. Up. IV, 5, 15).

Your assertion that the text 'Bliss is Brahman' (Taitt. Up. III, 6, 1)
proves pure Bliss to constitute the essential nature of Brahman is
