This beautifully illustrated authoritative guide to the Karma Kagyu lineage(and Tibetan Buddhism in general) was first published by KTD Publications on the 900th anniversary of the birth of the first Karmapa Dusum Khyenpa (1110 – 1193) and has since been translated into over a dozen languages.
The Gyalwang Karmapa has instructed that the revised 3rd edition now be made freely available
