Tsongkhapa Losang Drakpa was the founder of Gelukpa order, the most dominant religious sect in the history of Tibet. At the age of sixteen, he travelled from Tsongkha in Amdo to U-Tsang, central Tibet, a place where he came to influence greatly. He was a prominent teacher, philosopher, and yogi during a time when Buddhist intellectualism developed considerably. He emphasized the monastic code, reinterpreted Madhyamaka philosophy, inaugurated the Great Prayer Festival (Monlam Chemo), founded Ganden Monastery, and composed his most famous work, The Great Treatise on the Stages of the Path to Enlightenment (Lamrim Chenmo). His intellectual legacy changed the course of Tibetan history and is still very much alive.
