Here’s more on the lineage of the Dalai Lama. And by the way: HAR’s blog will keep you up-to-date on the website’s offerings, which seem to grow in scope every day. Students of Chokyi Nyima Rinpoche, for instance, might want to check out his great-grandfather’s page:
Choggyur Lingpa was a Terton, treasure revealer, of the 19th century and descended from the hereditary Baram Kagyu line. He was also a contemporary and friend to both Jamgon Kongtrul Lodro Taye and Jamyang Khyentse Wangpo. He discovered many ‘termas’ that are still popular within the Kagyu and Nyingma Traditions today.
Jeff Watt, director of Himalayan Art Resource, points us to a painting of Milarepa signed on the back by Choggyur Lingpa.
