Bhagavad Gita Chapter 3.16
evaḿ pravartitaḿ cakraḿ
nānuvartayatīha yaḥ
aghāyur indriyārāmo
moghaḿ pārtha sa jīvati
Translation
My dear Arjuna, one who does not follow in human life the cycle of sacrifice thus established by the Vedas certainly leads a life full of sin. Living only for the satisfaction of the senses, such a person lives in vain.
