Krishna is the Supreme Personality of Godhead. He is the son of Vasudeva and Devaki. Krishna appears on earth once in a day of Lord Brahma or once every 4,320,000,000 years. He is the source of Lord Vishnu, who is the source of all other incarnations of God.
His complexion is blackish, like the color of a new rain cloud. He stands in a three-fold bending form, dancing and playing on His flute. On the altar many times He will be with His consort, Radha. In paintings, He will be seen dancing with the cowherd girls (gopis), playing with the cowherd boys, or as Arjuna’s charioteer on the battlefield of Kurukshetra.
He killed the evil king Kamsa and many other demons to protect His devotees. He is the speaker of the Bhagavad-gita.
Krishna face is decorated with ornaments, such as earrings resembling sharks. Krishna’s ears are beautiful, His cheeks brilliant and Krishna’s smiling is attractive to everyone to see.” (Srimad Bhagavatam 9.24.65)
