Bhagavad Gita Chapter 3.28
tattva-vit tu mahā-bāho
guṇa-karma-vibhāgayoḥ
guṇā guṇeṣu vartanta
iti matvā na sajjate
Translation
One who is in knowledge of the Absolute Truth, O mighty-armed, does not engage himself in the senses and sense gratification, knowing well the differences between work in devotion and work for fruitive results.
