Tsongkhapa ("The man from Tsongkha", 1357–1419), usually taken to mean "the Man from Onion Valley", was a famous teacher of Tibetan Buddhism whose activities led to the formation of the Gelug school of Tibetan Buddhism. He is also known by his ordained name Losang Drakpa (Wylie: blo bzang grags pa ) or simply as "Je Rinpoche" (Wylie: rje rin po che ).
In his two main treatises, the Lamrim Chenmo (Wylie: lam rim chen mo ) and Ngakrim Chenmo (Wylie: sngags rim chen mo ), Tsongkhapa meticulously sets forth this graduated way and how one establishes oneself in the paths of sutra and tantra.
With a Mongolian father and a Tibetan mother, Tsongkhapa was born into a nomadic family in the walled city of Tsongkha in Amdo, Tibet (present-day Haidong and Xining, Qinghai) in 1357. It is said that the Buddha Sakyamuni spoke of his coming as an emanation of the Bodhisattva Manjusri in the short verse from the Root Tantra of Manjushri (Wylie: 'jam dpal rtsa rgyud ):
And my pure doctrine is absent,
You will appear as an ordinary being,
Performing the deeds of a Buddha
And establishing the Joyful Land, the great Protector,
In the Land of the Snows.
