Krishana is very kind. Therefore, He has given us his remnants of food stuff.
If you love Krishna in any capacity, you shall never be frustrated because everything in Krishna is perfect, eternal, blissful and full of Knowledge.
The Supreme Personality of Godhead, Krishna, appears in human society as an ordinary human being but acts very uncommonly for the well-being of the entire world.
Srimad Bhagavatam 7.10.70,
