Cleansing the Doors of Perception
The Religious Significance of Entheogenic
Plants and Chemicals

Huston Smith, internationally recognized philosopher, scholar of religion, and author of The World's Religions, now offers Cleansing the Doors of Perception, a course-correcting assessment of the connections among entheogens, religious experience, and the divinely inspired life.

A de luxe limited edition was published by the Council on Spiritual Practices. A trade cloth edition (Tarcher/Putnam) and a softcover edition (Sentient Publications) are available from booksellers everywhere.

The de luxe edition, limited to five hundred numbered and signed copies, was made by Stamperia Valdonega in Verona, the fine Italian press that produced the rare limited editions of Gordon Wasson's Ethnomycological Studies series, including Soma, The Wondrous Mushroom, and Persephone's Quest: Entheogens and the Origins of Religion.

Designed by Martino Mardersteig, this special edition of Cleansing the Doors of Perception is printed on Magnani mould-made paper, Smythe-sewn, bound in quarter leather with cloth sides and cloth covered slipcase by Ruggero Rigoldi, individually numbered on the letterpress, and signed by the author.


If the doors of perception were cleansed, every thing would appear to man as it is, infinite.
–William Blake


On this treacherous subject, where it is easy to go wrong, Smith has written a book that is as responsible as it is informed. His views are completely in accord with my own.
