Ronald Davidson, in addition to being co-editor, is a contributing author, “Preliminary Studies on Hevajra's Abhisamaya and the Lam-`bras Tshogs-bshad", pp.107-132.

Book Description: This volume consists of eight studies, each one bringing to light new material of use to comparative religionists and historians of religion, as well as to students of Tibetan Buddhism. These studies are based on critical scrutiny of indigenous sources and, in many cases, the learned opinion of native Tibetan scholars. The studies are organized around two dominant themes in Tibetan religious life -- the quest for clarity and insight via visionary exploration and philosophical exploration.
