It is seen, viz in Scripture, that those who knew Brahman busied
themselves chiefly with sacrifices.--Asvapati Kaikeya had a deep
knowledge of the Self; but when three Rishis had come to him to receive
instruction regarding the Self, he told them 'I am about, to perform a
sacrifice, Sirs' (Ch. Up. V, II). Similarly we learn from Smriti that
Janaka and other princes deeply versed in the knowledge of Brahman
applied themselves to sacrificial works, 'By works only Janaka and
others attained to perfection'; 'He also, well founded in knowledge,
offered many sacrifices.' And this fact--that those who know Brahman
apply themselves to works chiefly--shows that knowledge (or meditation)
has no independent value, but serves to set forth the true nature of the
active Self, and thus is subordinate to work.--An even more direct proof
is set forth in the next Sûtra.
