Shurei Sasai, a Buddhist monk from Japan, is working in India for the restoration of Buddhism, which claims that all people are equal.

The 89-year-old has been devoting his life to freeing people from discrimination based on the Indian caste system for more than half a century.

At a large-scale conversion ceremony held in the city of Nagpur in central India from Oct. 10 to 12, Sasai said in a strong voice that he will obey the way of Buddha, and his words were repeated by participants. To see one of the top leaders of Indian Buddhism, some 15,000 converts and 15 people from Japan who want to become monks attended the event.
