तच्छ्रुतेः ॥ ४ ॥
tacchruteḥ || 4 ||
tat-chruteḥ—Because the scriptures directly declare that.
4. That (viz. that knowledge of the Self stands in a subordinate relation to sacrificial acts) the scriptures directly declare.
“That alone which is performed with knowledge, faith, and meditation becomes more powerful” (Chh. 1. 1. 10); This text clearly shows that knowledge is a part of the sacrificial act.
