Premanand Maharaj Ji
Why does losing purity of character make bhajan feel joyless?
Protect character, chant the Name
When impure feeling enters character, even bhajan brings no joy or enthusiasm. Protect your character, chant the Name and walk in dharma, and your state will become like a yogi's.
One prayer: you are all young. Young people, protect your character, chant the Name and walk in dharma.
