Bhagavad Gita 2.51

2.51 The wise, possessed of knowledge, having abandoned the fruits of their actions, and being freed from the fetters of birth, go to the place which is beyond all evil.

By thus engaging in devotional service to the Lord, great sages or devotees free themselves from the results of work in the material world. In this way they become free from the cycle of birth and death and attain the state beyond all miseries [by going back to Godhead].
