Premanand Maharaj Ji
What is the real duty of a friend?
A friend's duty is to lead you to the right path
Making friends is not wrong, and a man can befriend a woman and a woman a man without fault. But a friend must turn you from the wrong path to the right one and support you, not exploit you.
Removing his problems and filling him with joy, helping him and not exploiting him, is what is called friendship.
