central Tibet and throughout his travels, he and his disciples made corrections and revisions of the Tibetan translations of Buddhist texts. In the process of giving teachings and making revisions and corrections of already-translated texts in western and central Tibet, Atisha acquired a Tibetan disciple, Dromtonpa, who is credited with establishing the Kadam tradition of Tibetan Buddhism, which Tsongkhapa (1357-1419) transformed into the Gelug school. Atisha passed away in Nyethang in central Tibet and his remains were preserved in a stupa. Tibet’s dismemberment into small principalities and domains during this time allowed the local rulers to inance individual Tibetan scholars to travel to India in search of Buddhist knowledge.

This text became the basic focus of study of the Sakya school of Tibetan Buddhism which Khon Kunchog Gyalpo, a student of Drokmi, founded. Another scholar and traveller was Marpa, (1012-1096). He had initially studied at the feet of Drokmi but decided to make his own expeditions to India and Nepal and eventually came across Naropa, with whom, according to one of Marpa’s own poems, he stayed sixteen years and seven months.
