Janmashtami is widely celebrated by Hindu Vaishnava communities of eastern and northeastern India. The widespread tradition of celebrating Krishna in these regions is credited to the efforts and teachings of 15th and 16th century Sankardeva and Chaitanya Mahaprabhu. They developed philosophical ideas, as well as new forms of performance arts to celebrate the Hindu god Krishna such as Borgeet, Ankia Naat, Sattriya and Bhakti yoga now popular in West Bengal and Assam. Further east, Manipur people developed Manipuri dance form, a classical dance form known for its Hindu Vaishnavism themes, and which like Sattriya includes love-inspired dance drama arts of Radha-Krishna called Raslila. These dance drama arts are a part of Janmashtami tradition in these regions, and as with all classical Indian dances, there contextual roots are in the ancient Hindu Sanskrit text "Natya Shastra", but with influences from the culture fusion between India and southeast Asia.Krishna Janmashtami Puja method
