Why Is There A Karma-Kanda Section Of The Vedas

“The rituals and sacrifices mentioned in the karma-kanda division of the Vedic literature are to encourage gradual development of self-realization. And the purpose of self-realization is clearly stated in the Fifteenth Chapter of the Bhagavad-gita (15.15): the purpose of studying the Vedas is to know Lord Krishna, the primeval cause of everything. So, self-realization means understanding Krishna and one's eternal relationship with Him.” (Shrila Prabhupada, Bhagavad-gita, 2.46 Purport)
