Chaitanya Mahaprabhu (Bengali: মহাপ্রভু শ্রীচৈতন্য দেব; Sanskrit: चैतन्य महाप्रभु, romanized: Caitanya Mahāprabhu), born Vishvambhara Mishra (IAST: Viśvambhara Miśra) (18 February 1486 – 14 June 1534), was an Indian Hindu saint from Bengal and the founder of Gaudiya Vaishnavism. Chaitanya Mahaprabhu's mode of worshipping Krishna with bhajan-kirtan and dance had a profound effect on Vaishnavism in Bengal.
He is considered the chief proponent of the Vedantic philosophy of Achintya Bheda Abheda. The concept of inconceivable difference in non-difference, known as achintya-bhedabheda, was explained later by Jiva Gosvami in his book Bhagavat Sandharbha, and in his Sarva-samvadini.
