 Radha and Krishna are avatars of Lakshmi and Vishnu respectively.While there are much earlier references to the worship of this form of God, it is since Jayadeva Goswami wrote a famous poem "Gita Govinda" in the twelfth century CE, that the topic of the spiritual love affair between the divine Krishna and his devotee Radha, became a theme celebrated throughout India.It is believed that Krishna has left the "circle" of the rasa dance to search for Radha.
