The Collected Works of Dusum Khyenpa, the first Karmapa, consists of four volumes of texts. The Collected Works is very rare, almost non-existent, but we obtained a copy. The Collected Works mostly contains complete sets of teachings on the various yidams of the Kagyu lineage that Dusum Khyenpa received and practised. However, there is a section containing eight dohas or spontaneous songs of spiritual realization that were sung by Dusum Khyenpa. There is also a text that gives the transmission of a specific Mahamudra teaching called Mahamudra, the Thunderbolt . We translated seven of the eight dohas and the Mahamudra teaching and put them together into this book, for the sake of the many followers of the Karmapa and the Kagyu teachings in general.
