From Bhagavad-Gita

He who has given up all the attachments, all fear, and all anger, he whose whole soul has gone unto the Lord, he who has taken refuge in the Lord, whose heart has become purified, with whatsoever desire he comes to Lord, HE will grant that to him. Therefore worship HIM through knowledge, love or renunciation.

He who hates none, who is the friend of all, who is merciful to all, who has nothing of his own, who is free from egoism, who is even-minded in pain and pleasure, who is forbearing, who is always satisfied, who works always in Yoga, whose self has become controlled, whose will is firm, whose mind and intellect are given up Unto Me, such a one is my Beloved Bhakta. From whom comes no disturbance, who cannot be disturbed by others, who is free from joy, anger, fear, and anxiety, such a one is My Beloved. He who does not depend on anything, who is pure and active, who does not care whether good comes or evil, and never becomes miserable, who has given up all efforts for himself, who is the same in praise or in blame, with a silent, thoughtful mind, blessed with what little comes in his way; homeless, for the whole world is his home, and who is steady in his ideas, such a one is My Beloved Bhatka, such alone become Yogis.
