Compares the metaphysical and mystical thought-systems of Sufism and Taoism and discovers that, although historically unrelated, the two share features and patterns which prove fruitful for a transhistorical dialogue. This book offers an analysis of parallel concepts of two great Taoist thinkers, Lao-tzu and Chuang-tzu.
"Professor Izutsu's work is a pioneering attempt to bring into focus the shareable philosophical concerns of two seemingly unrelated landmarks into religious thought. His method is suggestive, interpretation new and bold, and material used important for further research. His book is useful to students of comparative religion, philosophy of religion, cultural anthropology, Asian thought and religion, and Islamic and Taoist studies."-Tu Wei-ming
"[This book] carries out a comparison in depth between Islamic and Chinese thought for the first time in modern scholarship. . . . Since this book appeared it has influenced every work on Ibn 'Arabi and metaphysical Sufism...[and] any cursory study of Sufism during the last fifteen years will reveal the extent of Izutsu's influence."-Seyyed Hossein Nasr
