Śāntideva

A monk at Nālandā whom his brothers thought did nothing but eat and sleep, until they invited him to teach as a joke and he recited the Bodhicaryāvatāra from the seat. Its argument is a strange, sharp piece of logic: if suffering is bad, it is bad wherever it occurs, and the boundary marked "me" gives it no special weight.

The great manual of the bodhisattva vow, and the closest thing on this bench to tikkun olam reached from an opposite metaphysics.
