Where the texts speak of Brahman as having four quarters, and sixteen
parts, or say that 'one quarter of him are all these beings' (Ch. Up.
III, 12, 6), they do so for the purpose of thought, i.e. meditation,
only. For as texts such as 'the Truth, knowledge, infinite is Brahman'
teach Brahman, the cause of the world, to be unlimited, it cannot in
itself be subject to measure. The texts referring to measure therefore
aim at meditation only, in the same way as texts such as 'Speech is one
foot (quarter) of him, breath another, the eye another, the mind
another' (Ch. Up. III, 18, 2).--But how can something that in itself is
beyond all measure, for the purpose of meditation, be spoken of as
measured? To this the next Sûtra replies.
