Premanand Maharaj Ji
I am afraid of old age and death. What should I do?
Turn the fear of death into bhajan
If this fear truly settles in you, it can lead to your welfare. Go to a guru and begin chanting the Name of Bhagwan.
Being afraid, go to the guru's refuge and begin chanting the Name. Begin bhajan of Bhagwan and it will be auspicious for you.
