Liberation Through Renunciation — Moksha Upadesha Yoga
Chapter 18 of Bhagavad Gita by Vyasa
Fain would I better know, Thou Glorious One! The very truth--Heart's Lord!--of Sannyas, Abstention; and enunciation, Lord! Tyaga; and what separates these twain!
The poets rightly teach that Sannyas Is the foregoing of all acts which spring Out of desire; and their wisest say Tyaga is renouncing fruit of acts.
There be among the saints some who have held All action sinful, and to be renounced; And some who answer, "Nay! the goodly acts-- As worship, penance, alms--must be performed!" Hear now My sentence, Best of Bharatas!
