Bhagavad Gita 3.16

एवं प्रवर्तितं चक्रं नानुवर्तयतिह य: |
अघायुरिन्द्रियरामो मोघं पार्थ स जीवति

Translation

O Parth, those who do not accept their responsibility in the cycle of sacrifice established by the Vedas are sinful. They live only for the delight of their senses; indeed their lives are in vain.
