Song is the ultimate offering ...

|| Japakoti gunam dhyanam - dhyanakoti gunolayas

   Laya koti gunam ganam - ganat parataram nahi || 

Meaning: Meditating just once is worth chanting verses a million times.

Being in the state of divine union once is worth meditating a million times.

A song sung in true harmony is worth being in the state of divine union a million times

There is nothing greater than song. 

True songs and poems originates from the bliss of the singer who is in a prolonged state of divine union. The saints and seers in the Indian sub continent sang innumerable songs of love, devotion and beauty. These songs form the basis of classical music in India. Singing is therefore considered the ultimate form of worship.
