Madhvaon Brahma Sūtra 1.4.18

Jaimini thinks that the words declare even actions, etc., so as to produce the knowledge of the Lord ; for in the Atharvanopanishad, the question is asked. “ O, Venerable one, what is that (thing) which if (properly) known, would lead to a clear understanding of all this.” And the answer follows in the text, “ To him he gladly said f there are two kinds of study to be pursued ’ (there are two kinds of knowledge to be acquired)”. Again in the Chandogya the question and answer occur thus, *« O Venerable one, how now may I secure that instruction, etc.—Just as by knowing a piece of earth all earth is known, etc.” (Ch. VI. 1). So also some Sakhins read, “ What could he who does not know that (Brahman) do with the Rik (of what avail is Rik to him, who does not understand that they all refer to Brahman) ” (Rv. I 164-39.) • [“Objection :—For the knowledge of Brahman, Karma and other things need not be spoken of in the Vedas; and it would be sufficient to speak of Him alone, while the difficulty of construing all the Vedas as declaring Brahman is got over by admitting that only detached words denote other things.

To remove this objection, the following Sutra proceeds.]
