Premanand Maharaj Ji
Why is worrying useless when Bhagwan runs everything?
The man running inside the train
Someone running inside a moving train makes no difference to the train or the journey; he only tires himself. Worry is the same, so do bhajan and good deeds instead of worrying.
He is running inside the carriage for nothing. What difference will his running make to the train? To the journey? He is only taking tiredness for nothing. You are taking the tiredness of worry for nothing.
