69.61

佛告比丘。古今以來。天地成立。無免此苦。四難之患。以斯四苦。佛興于世。

The Buddha told the monks: "From ancient times until now, ever since heaven and earth were established, none has escaped these sufferings, the calamities of these four difficulties. It is because of these four sufferings that a Buddha appears in the world."
