In April 1931 Govinda went to All-India Buddhist Conference in Darjeeling as the representative of the IBU, to propagate the "pure Buddhist teaching as preserved in Ceylon, in a country where it had degenerated into a system of demon worship and fantastic forms of belief." However, in nearby Sikkim he met the Tibetan Gelugpa meditation teacher Tomo Geshe Rimpoche alias Lama Ngawang Kalzang (1866–1936), who greatly impressed him and completely changed his views about Tibetan Buddhism. From then on he embraced Tibetan Buddhism, although he never abandoned his Theravada roots and stayed in contact with Nyanatiloka and later with Nyanaponika. Lama Ngawang Kalzang taught meditation to Govinda, who remained in contact with him until his death. During their 1947–1948 expeditions to Tibet, Govinda and Li Gotami met Ajo Repa Rinpoche, who, according to Govinda, initiated them into the Kagyüpa school of Tibetan Buddhism.
