Who is Krishna?

God is described as the "param ishwar" or the supreme controller. There are many controllers or isvaras in the universe, like Vayu who controls the air, Indra who controls the rain and Surya who controls the Sun. But all these controllers are in turn controlled by some one else and if go up the chain we finally reach the supreme controller, one who directly or indirectly controls every one, but has no controller.
 

This supreme controller is ultimate origin of everyone and everything. He has no other origin and He is the cause of all causes. Lord Brahma states that this supreme controller, is Krishna, also known as Govinda.
