In plain words
Do action; there is nothing wrong in it. It is not negative. But it is bondage only when you set your mind on the fruit of the actions. Only then does it turn negative. Do all actions without bondage. All of it becomes positive. It becomes God's own work. You must put this body God has given into good deeds and think of whatever work you do as God's work. God gave this body for this action. Whether good or bad, to take God's command upon one's head is duty. To push one's personality aside and carry out one's duty is the true positive. But today it is not so. Man puts his personality in the front. So he falls into every sorrow. He falls into every bondage. He sinks down under every kind of sorrow. The state in which man neither sinks nor swells is to carry out his true duty. Put your personality aside.
I have told you many times. In the old days there was a film actor called Nagayya. He played the part of Tyāgayya. When he played Tyāgayya and sang, people enjoyed it. But it was the name Tyāgayya that stayed; the name Nagayya was wiped out. Only when someone asks "Who played Tyāgayya?" does the name come up: "Nagayya played him." At the time of acting on the stage, at the time of singing, he is Tyāgayya, not Nagayya. The physical world is a stage for a play. In it you must put your personality aside. You must keep proper security in the principle of the jīva. The principle of the jīva is the true security. That is the positive. Where the bondage called negative comes, there it becomes bondage. To grow the sense of mine, saying "I, I," is the great bondage. What is "I"? Which is you? Are you Manas? Are you Buddhi? Are you the antaḥkaraṇa? When you question yourself in this way, none of these is you. Then who are you? "I am I": that is the true positive. I am doctor, I am engineer, I am lecturer. All such things come for a time. You must put this personality aside. Students must make the effort from today itself. Parents may be somewhat troubled: "Why do they teach Mukti, Mukti, at such a young age?"
