The Bhagavad Gita [translated by W J Johnson]

He who has inner happiness, inner delight, and thereby inner radiance – that yogin, being Brahman, achieves the nirvana of Brahman

Seers whose impurities have been destroyed, whose doubts have been dispelled, who have restrained themselves, who delight in the welfare of all beings, reach the nirvana of Brahman.

The wise man, whose senses, mind and intelligences are controlled, who is wholly intent upon release, whose desire, fear and anger have vanished is liberated forever.

But striving with great effort, the yogin whose defilement has been purified is perfected through many lives, and then he attains the highest goal.

The yogin is considered superior to men of knowledge; the yogin is considered superior to those engaged in action.

Therefore be a yogin Arjuna!
