The Book of Pleasure: The Psychology of Ecstasy

The Book of Pleasure: The Psychology of Ecstasy is a book written by Austin Osman Spare during 1909-1913. The book could be regarded the central text among his writings. It covers both mystical and magical aspects of Spare's ideas; and the modern ideas on sigils (as now have become popular in chaos magic) and Spare's special theory on incarnation are for the first time introduced in this book.
