Premanand Maharaj Ji
I try to remember Bhagwan, but useless worries and fear still stay. What should I do?
Keep chanting with effort
The mind is still impure, so worries of past, future and the world come while you do bhajan. Chant the Name you love, forcefully and continuously, and you will rise above this state.
Don't worry; contemplate. Hari Himself will take care of your worries.
