The name comes from the Sanskrit word (कृष्ण) [Krsna] - "black, dark, dark-blue; wicked".
Krishna (or Krushna) - is a Hindu deity, regarded as an avatar of Vishnu and in some monotheistic traditions considered the Supreme Being.
Krishna is often depicted as an infant or young boy playing a flute as in the Bhagavata Purana, or as a youthful prince giving direction and guidance as in the Bhagavad Gita. The stories of Krishna appear across a broad spectrum of Hindu philosophical and theological traditions. They portray him in various perspectives: a god-child, a prankster, a model lover, a divine hero and the Supreme Being. The principal scriptures discussing Krishna's story are the Mahabharata, the Harivamsa, the Bhagavata Purana and the Vishnu Purana. Krishna changed his original name Nandanandana (meaning son of Nanda) into Krishna.
