વસુદેવસુતં દેવં

This is a prayer to Lord Krishna, as the Guru of the entire universe. It is the beginning verse of Krishnashtakam. This verse describes the four important people in the life of Sri Krishna who would soon reveal himself as the Jagad Guru. Those four individuals are Vasudeva and Devaki (his parents), Kamsa (His maternal uncle and evil adversary since birth) and Chanura, a formidable and evil wrestler. Krishna was separated from his parents at birth, had to deal with Kamsa who was out to kill him by any means possible and fight with and defeat Chanura when he was a mere boy.
