UJetsun Milarepa (Tibetan: རྗེ་བཙུན་མི་ལ་རས་པ, Wylie: rje btsun mi la ras pa) (c. 1052 – c. 1135 CE) is generally considered one of Tibet's most famous yogis and poets. He was a student of Marpa Lotsawa, and a major figure in the history of the Kagyu school of Tibetan Buddhism.
Born in the village of Kya Ngatsa – also known as Tsa – in Gungthang, a province of western Tibet, to a prosperous family, he was named Mila Thöpaga (Thos-pa-dga'), which means "A joy to hear." His family name, Josay, indicates noble descent, a sept of the Khyungpo or eagle clan.
When his father died, Milarepa's uncle and aunt took all of the family's wealth. At his mother's request, Milarepa left home and studied sorcery. While his aunt and uncle were having a party to celebrate the impending marriage of their son, he took his revenge by summoning a giant hailstorm to demolish their house, killing 35 people, although the uncle and aunt are supposed to have survived. The villagers were angry and set off to look for Milarepa, but his mother got word to him, and he sent a hailstorm to destroy their crops.
Many of Milarepa's deeds took place in the homeland of Chö kyi Drönma, the Samding Dorje Phagmo, and his life and songs were compiled by Tsangnyön Heruka, sponsored by her brother, the Gungthang king Thri Namgyal De.
Milarepa later lamented his evil ways in his older years in conversation with Rechungpa: "In my youth I committed black deeds. In maturity I practised innocence. Now, released from both good and evil, I have destroyed the root of karmic action and shall have no reason for action in the future. To say more than this would only cause weeping and laughter. What good would it do to tell you? I am an old man. Leave me in peace."
