He who is free from wants, who is pure, efficient, unattached, untroubled and has given up all (selfish) undertakings — he who is thus devoted to Me is dear to Me. (Bhagavad Gita Chapter 12 verse 16).
He who is free from expectations, free of wants – how happy he is! Trusting in Bhagavan, he is not worried about the future. The yogi is clever, he possesses presence of mind and sound judgment. He is efficient, alert, alive, and not dull and stupid. He is prompt and quick in matters demanding prompt action. He does not sway from his purpose. Nothing can trouble or disturb him. He abandons all selfish undertakings calculated to secure objects of desire in this world or even the next. He who thus serves Bhagavan is dear to Him.
