Wisdom from the Bhagavad Gita 52

Arjuna said: 

21. By what marks, O Lord, is he known who has gone beyond these three Gunas? What is his conduct, and how does he pass beyond these three Gunas? 

The Blessed Lord said: 

22. He who hates not the appearance of light (the effect of Sattva), activity (the effect of Rajas), and delusion (the effect of Tamas), in his own mind, O Pândava, nor longs for them when absent; 

23. He who, sitting like one unconcerned, is moved not by the Gunas, who, knowing that the Gunas operate, is Self-centred and swerves not; 

24. Alike in pleasure and pain, Self-abiding, regarding a clod of earth, a stone, and gold alike; the same to agreeable and disagreeable, firm, the same in censure and, praise; 

25. The same in honor and disgrace, the same to friend and foe, relinquishing all undertakings—he is said to have gone beyond the Gunas. 

26. And he who serves Me with an unswerving devotion, he, going beyond the Gunas, is fitted for becoming Brahman. 

27. For I am the abode of Brahman, the Immortal and Immutable, of everlasting Dharma and of Absolute Bliss. 

—Bhagavad Gita, 14:21-27
