Premanand Maharaj Ji
When someone else gets ahead of me in competition, how do I stop feeling jealous?
See the one ahead as your own brother
Jealousy is not right. It leads to ill-will, and ill-will leads to sin, so do not treat the one ahead as an outsider. Bhagwan gave him the ability, and when he gives you yours, you will move ahead too.
If your brother were moving ahead, you would be happy, wouldn't you? Why consider him someone else? Don't consider him other. Bhagwan gave him the ability, and he is moving ahead.
