Je Tsongkhapa

Tsongkhapa was an influential Tibetan Buddhist monk, philosopher and tantric yogi, whose activities led to the formation of the Gelug school of Tibetan Buddhism. He is also known by his ordained name Losang Drakpa or simply as "Je Rinpoche". He is also known by Chinese as Zongkapa Lobsang Zhaba or just Zōngkābā.
Tsongkhapa was born in Amdo, the son of a Tibetan Longben Tribal leader who also once served as an official of the Yuan dynasty. It is said that Tsongkhapa's father was probably a Mongolian because he was the head of a Tibetan tribe of the Yuan dynasty. It is possible that a Tibetan philosopher was born from the family of a Mongolian leader. As a monk, Tsongkhapa studied under numerous teachers of the various Tibetan Buddhist traditions which flourished in central Tibet, including Sakya, Jonang, Kagyu and Kadam.
Tsongkhapa was a prolific author with a broad knowledge of Buddhist philosophy, logic, hermeneutics and practice. He wrote numerous works on madhyamaka philosophy, Mahayana practice, and Vajrayana.
