"The Great Tao" can be defined s "The Heavenly Way" or in another word, "Truth". "Truth can be defined as One's "Conscience". In Chinese, "The Great Tao" is called "天道"which is very valuable and should be sought by all mankind.

"The Great Tao" tells us actually where our soul comes from and where our soul should return to, in the future. "The Great Tao" also prevents us from doing bad things because whenever we have any bad internal or external intentions, we should seek our "Teacher" (The Secret Place where out "Conscience" actually lies in Chinese, we call "良心") whether is it worth doing it and thereby committing a sin for which we will be punished for the various sins committed in hell accordingly when we depart from this world.

"The Great Tao" was established many thousands of years ago and it was brought down from many generations. People at that time during "The Green Stage" have to be extremely good and also they have to undergo tremendous sufferings before they can attain 'The Secret of the Great Tao".
