Bhagavad Gita 3.16 — Keep the wheel turning
एवं प्रवर्तितं चक्रं नानुवर्तयतीह यः। अघायुरिन्द्रियारामो मोघं पार्थ स जीवति ॥
evaṃ pravartitaṃ cakraṃ nānuvartayatīha yaḥ | aghāyurindriyārāmo moghaṃ pārtha sa jīvati ||
Meaning
One who does not help keep this wheel turning, Partha, lives in sin, delighting only in the senses, and lives in vain.
