Bhajans are highly sacred. Bhajan singing makes the heart sacred. What is important is that it should come out from the heart. Bhajan is not just rhythm, tune and beat.

You should sing God's name with love. You will see the manifestation of divinity with your physical eyes when you sing his glory with all Love.
