Evam bahu-vidha yajna
vitata brahmano mukhe
karma-jan viddhi tan sarvan
evam jnatva vimoksyase
(Bhagavad Gita, Text 32, Ch 4, Transcendental Knowledge)
Different types of sacrifice mentioned in the Vedas suit different types of worker. Because men are so deeply absorbed in the bodily concept, these sacrifices are so arranged that one can work either with the body, with the mind, or with the intelligence. But all of them are recommended for ultimately bringing about liberation from the body.This is confirmed by the Lord herewith from his own mouth.
