Explanation:

 With the arrival of Vaishnavism in the 15th century A.D., new compositions based on episodes from the life of Radha and Krishna were gradually introduced. It was in the reign of King Bhagyachandra that the popular Rasleela dances of Manipur originated. It is said, that this 18th century philosopher king conceived this complete dance form along with its unique costume and music in a dream. Under successive rulers, new leelas, and rhythmic and melodic compositions were introduced. Manipur dance has a large repertoire; however, the most popular forms are the Ras, the Sankirtanaand the Thang-Ta. There are five principal Ras dances of which
four are linked with specific seasons, while the fifth can be presented at any time of the year. In Manipuri Ras, the main characters are Radha, Krishna and the gopis.
