In 1974, the oldest extant copy of Lao Tzu's Tao Te Ching (6-4th century BCE) was unearthed at Xi' an along with the ceramic warriors guarding the tomb of the first Chinese Emperor Qin Shi Huang. By 1979, Professor Toshihiko Izutsu-- the Japanese Islamicist, philosopher and linguist-- collaborated in Tehran with Seyyed Hossein Nasr to translate this treasure into English. Dr. Nasr went on to put it into Persian adding a Sufi commentary which was recently published in Iran. This has now been translated into English with annotations by Mohammad H. Faghfoory.

Just as the original English translation of the Tao Te Ching presented here was the fruit of a collaboration between a Japanese and Persian scholar, and through Nasr's translation and commentary into Persian, this book becomes the scene of an encounter between Islamic and Chinese religions and civilizations as well as Persian culture where Qur' anic verses, verses of the Tao Te Ching and Persian Sufi poetry and prose stand side by side. " A Sufi Commentary on the Tao Te Ching, penned by the greatest living Muslim philosopher Seyyed Hossein Nasr, enshrines nothing less than a fulfilment of the Proph
