These two verses are quoted from Srimad-Bhagavatam (11.21.42-43). When Uddhava asked Krishna about the purpose of Vedic speculation, the Lord informed him of the process of understanding the Vedic literature. The Vedas are composed of karma-kanda, jnana-kanda and upasana-kanda. One who analytically studies the purpose of the Vedas understands that by karma-kanda, sacrificial activity, one comes to the conclusion of jnana-kanda, speculative knowledge, and that after speculation one comes to the conclusion that worship of the Supreme Personality of Godhead is the ultimate. When one comes to this conclusion, he becomes fully satisfied.
