Bhagwad Gita
Chapter 3, Verse 28
तत्त्ववित्तु महाबाहो गुणकर्मविभागयोः।
गुणा गुणेषु वर्तन्त इति मत्वा न सज्जते।।3.28।।
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.
