The Tao Teh Ching is one of the most frequently translated and most cherished works in the world. This ancient Chinese classic, written around 500 B.C., presents the core of Taoist philosophy and provides a bridge to the subtle truth as well as a practical guideline for natural and harmonious living. It is generally believed that Lao Tzu left behind only a single work, the Tao Teh Ching. Few people are aware that some of his later teachings were recorded (also around 500 B.C.) in a book entitled the Hua Hu Ching. During a time of political turmoil in the 14th century, all copies of this work were banned and ordered to be burned. Consequently, few, if any, complete and accurate copies exist today. Fortunately, the complete teachings of the Hua Hu Ching have been preserved through the oral transmission of generation after generation of Taoist Masters to their disciples. Master Ni, heir to that orally transmitted wisdom, has translated the Hua Hu Ching and also the Tao Teh Ching. Both works are now available in one volume, The Complete Works of Lao Tzu. Hua-Ching Ni is fully acknowledged and empowered as a true teacher of natural spiritual truth by his own spiritual attainment rather than by external authority. He is a model of spiritual achievement through spiritual self-cultivation. He is also heir to the wisdom transmitted through an unbroken succession of numberless generations of masters dating back to many generations before Christ. As a young boy, he was educated in spiritual learning by his family and then studied with teachers, recluses and hermits in the high mountains of China, fully achieving all aspects of ancient spiritual science and metaphysics. His teaching differs from conventional folk religious promotion. He teaches the Integral Truth which aims to serve people in all aspects of life. Hua-Ching Ni considers that his teaching is the product of years of his spiritual cultivation, and offers it to people to support their own path of growth. Here is what Master Ni says about himself: `I was not especially gifted and encouraged. What I attained was through hard work and a challenging life. I have dedicated my life to support people who come through a hard life and grow through diligent learning. This is my personal offering to all my friends.`
