The Tao Te Ching or Dao De Jing, whose authorship has been attributed to Laozi, is a Chinese classic text. Its name comes from the opening words of its two sections:

? dào "way," Chapter 1, and

? dé "virtue," Chapter 38

plus ? j?ng "classic."

According to tradition, it was written around the 6th century BC by the sage Laozi (or Lao Tzu, "Old Master"), a record-keeper at the Zhou Dynasty court, by whose name the text is known in China.   (from Wikipedia)

The core concept in the whole philosophy of Dao De Jing, is crystalised in the concept of "DAO" which can be better translated in to: "The Way Of Nature" which is parallel (in definition) to the concept of "Yin-Yang".

"Dao De Jing" has been translated by several scholars. The words and terms used in the book have many years of history and very colourful background which unfortunately have been lost through the ages passed from the first time it was written.

In addition to this loss of information, the text has been viewd mostly by the people from Europe and States, who were looking in to the words with a Western Paradigms in mind.

Thus, the meaning of the words and hence the whole chapters have been considerabley lost in it's new age translations.

Ali Soleymaniha, an organisational change management expert, has devoted a considerable amount of time digging down the history to understand each one of the words used to create this "Body of Knowledge".
