Premanand Maharaj Ji
I get scared when I am alone at night. How do I stop this fear?
God is with you when you are alone
Worship of God exists to remove this kind of fear. God is everywhere, so He is with you even when no one else is. He will protect you because you are His devotee and do naam jap.
God is all-powerful, so He will protect you, because you wear the kanthi (devotee's neck beads), you are God's devotee and you do naam jap. So what is there to fear?
