The Two Truths in Bon is an innovative survey of Madhyamika’s two truths theory of the Bön religion in comparison with Indian and Tibetan Madhyamika. Since 1960’s Bonpo Study has developed rapidly in western countries. Concerning its doctrine, they seem to have focused on Vajrayana and dzogchen. On the other hand, the study on Sutrayana has been left behind. Madhyamika philosophy is the fundamental basis of Vajrayana and dzogchen, and the two truths is the basic theory (gzhi) of Madhyamika. The Two Truths in Bon is the first comprehensive study published in western language on Bönpo Madhyamika philosophy. In the Introduction, Seiji Kumagai provides an overview of the general history of the two truths in Indian Buddhism and Tibetan Buddhism. This is also helpful to understand how Bönpo thinkers were influenced by Buddhist doctrine and how they have created their own theory.
It is for the first time that a study of Madhyamaka philosophy in its Bön interpretation has now been published. This book provides an overview of the general history of the two truths in Indian Buddhism and Tibetan Buddhism.
