contrary to the meanings of the several words, and that thus they have
meaning and unity of meaning and yet are not mere synonyms. The details
are as follows. Brahman is to be defined as what is contrary in nature
to all other things. Now whatever is opposed to Brahman is virtually set
aside by the three words (constituting the definition of Brahman in the
Taittiriya-text). The word 'true' (or 'truly being') has the purport of
distinguishing Brahman from whatever things have no truth, as being the
abodes of change; the word 'knowledge' distinguishes Brahman from all
non-sentient things whose light depends on something else (which are not
self-luminous); and the word 'infinite' distinguishes it from whatever
is limited in time or space or nature. Nor is this 'distinction' some
positive or negative attribute of Brahman, it rather is just Brahman
itself as opposed to everything else; just as the distinction of white
colour from black and other colours is just the true nature of white,
not an attribute of it. The three words constituting the text thus _have_
a meaning, have _one_ meaning, and are non-synonymous, in so far as they
convey the essential distinction of one thing, viz. Brahman from
everything else. The text thus declares the one Brahman which is
self-luminous and free from all difference. On this interpretation of
the text we discern its oneness in purport with other texts, such as
'Being only this was in the beginning, one only, without a second.'
Texts such as 'That from whence these beings are born' (Taitt. Up. III,
1); 'Being only this was in the beginning' (Ch. Up. VI, 2, 1); 'Self
alone was this in the beginning' (Bri. Up. I, 4, 1), &c., describe
Brahman as the cause of the world; and of this Brahman the Taittiriya
passage 'The True, knowledge, infinite is Brahman' gives the strict
definition.

In agreement with the principle that all sakhas teach the same doctrine
we have to understand that, in all the texts which speak of Brahman as
