He whom the world troubles not, and who troubles not the world, who is free from the emotions of joy, wrath, and fear, is dear to Me. The man who is guileless, pure, upright, unconcerned, free from distress of mind, who renounces every enterprise and worships Me, is dear to Me. He who has neither delight nor aversion, who neither mourns nor desires, who renounces good and evil fortune, and worships Me, is dear to Me. He who is the same to friend and foe, and also in honor and dishonor, who is the same in cold and heat, pleasure and pain, who is wholly free from attachment; To whom praise and blame are equal, who is silent, content with every fortune, home-renouncing, steadfast in mind, and worships Me, that man is dear to Me.
Bhagavad Gita 12:15-19
