Bhagavad Gita 4.32

4.32 Thus, manifold sacrifices are spread out before Brahman (literally) at the mouth or face of Brahman). Know them all as born of action and thus knowing, thou shalt be liberated.

All these different types of sacrifice are approved by the Vedas, and all of them are born of different types of work. Knowing them as such, you will become liberated.
