Milarepa, Tibet's greatest meditation master, lived as a yogi at the end of the eleventh century. Born into affluence, Milarepa watched as their estate was stolen by an ambitious uncle. To avenge this injustice, Milarepa mastered the arts of black magic and assassinated his uncle's family and friends. Almost immediately Milarepa felt great remorse for his brutality and set out to undo his bad karma. Guided by a spiritual teacher named Marpa, Milarepa endured many physical hardships and mental challenges designed to purify his negative actions.
