Krishna (/ˈkrɪʃnə/; Sanskrit: कृष्ण, Kṛṣṇa in IAST, pronounced [ˈkr̩ʂɳə]) is a Hindu deity, worshipped across many traditions of Hinduism in a variety of different perspectives. Krishna is recognized as the eighth avatar of the god Vishnu or as the Supreme God in other traditions. Krishna is one of the most widely revered and most popular of all Hindu deities.Krishna is often described and portrayed as an infant eating butter, a young boy playing a flute as in the Bhagavata Purana, a young man along with Radha or as an elder 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. Worship of the deity Krishna, either in the form of deity Krishna or in the form of Vasudeva, Bala Krishna or Gopala can be traced to as early as the 4th century BC. Worship of Krishna as Svayam Bhagavan, or the supreme being, known as Krishnaism, arose in the Middle Ages in the context of the Bhakti movement. From the 10th century AD, Krishna became a favourite subject in performing arts and regional traditions of devotion developed for forms of Krishna such as Jagannatha in Odisha, Vithoba in Maharashtra and Shrinathji in Rajasthan. Since the 1960s the worship of Krishna has also spread in the Western world and in Africa largely due to the International Society for Krishna Consciousness.
