This book opens the way to a deeper knowledge of mahamudra, a Buddhist system of meditation on the nature of the mind. In providing a detailed commentary on the Vajra Song of the first Jamgön Kongtrül (1813–1899), the author elucidates the stages of ground, path, and fruition for those who wish to meditate according to this system.
Jamgön Kongtrül is a name of a prominent line of Tibetan Buddhist teachers (lama), primarily identified with the first Jamgon Kongtrul, but also the name shared by members of a lineage held by tradition to be his subsequent reincarnations (tulku), to date.
The first Jamgon Kongtrul, Jamgön Kongtrül Lodrö Thayé, was one of the preeminent scholars in 19th century Tibet. Tibetan Buddhists believe that he had multiple simultaneous emanations; only one of these, Khyentse Özer, was called the second Jamgon Kongtrul. The recognition of the fourth Jamgon Kongtrul is presently in dispute, complicated by the ongoing controversy regarding the recognition of the genuine reincarnation of H.H. the 17th Karmapa.
