“Marco Pallis was at once an incomparable authority on Buddhism, especially in its Tibetan form, a defender and protector of the Tibetan tradition in the west since the tragedies of 1951, a lover of nature and a mountain climber who first encountered Tibetan Buddhism while climbing Himalayan peaks in the 1920s, a profound student of other religions, especially Christianity, and a very accomplished musician…All of these concerns of Pallis are reflected in A Buddhist Spectrum. It is a Buddhist work on both religion as such and religions in their multiplicity. A major characteristic of the book is that it is concerned with the reality of Buddhism and not just a theoretical analysis of its ideas. A Buddhist Spectrum is a wise book while being thoroughly reliable from a scholarly point of view.” (Seyyed Hossein Nasr, George Washington University)
