Only by understanding Dao (the Way of Nature) and dwelling in its unity can humankind achieve true happiness and freedom, in both life and death. This is the central tenet of the philosophy espoused by Zhuangzi (369?-286?BC) in the book that bears his name. A leading philosopher of the Daoist strain, Zhuangzi used parable and anecdote, allegory and paradox, to set forth the early ideas of what was to become the Daoist school. Witty and imaginative, enriched by brilliant imagery, and making sportive use of both mythological and historical personages (including even Confucius), this is a timeless classic.
