Written around 500 BC, the Tao Teh Ching is one of the most frequently translated and most cherished works in the world. The Complete Works of Lao Tzu by Master Ni is a remarkable elucidation of the famed Tao Teh Ching. It is the only known written record of Lao Tzu's orally transmitted teaching, the Hua Hu Ching. As the only book of Lao Tzu written by a Taoist Master in the English language, it is little wonder it is one of our most popular books.
