this is one of the most interesting things to learn about the modern asian world, especially japan.
buddhisness is the business which lets the priests of big buddhist temple's gain incredible wealth, basically through donations.
priest: i'm a buddhist priest, you know. today's buddhism is like a usual service business. a temple lives primarily from donations. the largest amounts are contributed at funerals. so the more people of my religion that die each month the better for me. one may call this buddhisness ;)
