“The Sena kings, who followed the Palas in the dominion over Eastern India, though belonging to Hindu persuasion, were not hostile to the Faith. Still Buddhism declined during their reign, and more so after the invasion of the country by the Mohammedans in A.D. 1200. The monasteries of Udandapura and Vikramsila were destroyed; the monks were killed, or they fled to other countries The learned Sakyasri went to Orissa and afterwards to Tibet; Ratnarakshita to Nepal; Buddhamitra and others sought a refuge in South India, whilst Sangama-Srijnana with several of his followers betook themselves to Burma, Camboja, etc. And thus the law of Buddha became extinct in Magadha.
