The Underlying Religion is an anthology of 25 essays by 14 of the leading exponents of the "e;perennialist"e; or "e;traditionalist"e; school of comparative religious thought, associated with Rene Guenon, Ananda Coomaraswamy, and Frithjof Schuon. This school is well known for its espousal of the "e;transcendent unity of religions"e;-the idea that religions are different paths leading to the same summit. Focusing its selection on the most accessible of the perennialist writings, and structured in such a way as to allow for the easiest possible comprehension, The Underlying Religion aims to be the most accessible introduction yet to the perspective of the Perennial Philosophy.
