Nechung Rinpoche Ogyen Thinley Choephel came from Mindroling Monastery to Nechung Monastery in the 1880's. His coming to Nechung was due to the unflagging grace of the great Dharma protector, and in particular his unique practice of the Treasured Doctrine. This happened during the time of the Eighth Medium, Shakya Yarphel. Rinpoche not only became the medium's spiritual guide, but also of Nechung's sangha, to whom he passed extensive transmission of the meditation practices on the energy channels, wind, and yantras (Tsa-Lung, Khrul-Khor) of the generation and completion stage practices of tantra.
