Behold the Spirit: A Study in the Necessity of Mystical Religion, a book by Alan Watts (1915–1973), was first published in 1947 by John Murray Publishers (London). This book is a reworking of Watts' Episcopal divinity degree thesis. Its importance lies partly in its exposition of Watts' earliest attempt to reconcile traditional Anglican theology with a mystical, Buddhist based approach, but also as a personal expression of the mystical experience.
