Yogapedia explains Hari
Hari is also known as Krishna, Ram, Hari Krishna and Vahguru. In Hinduism, Hari is depicted with the skin color of pale blue like a dark cloud, sometimes lending him the name “The Dark One.” Hari is often portrayed holding a lotus, discus, conch and mace in his hands. Hari is found in the Hindu texts such as the Bhagavad Gita and "Mahabharata."
According to Hindu legend, Hari was a romantic and was heard to make thousands of copies of himself in order to dance with multiple maidens alone, although he ended up falling in love with just one: the goddess, Radha.
