"The Tao", also known as "The Tao Teh King", by "Lao-Tse", also known as "Laozi". "Scholars of the highest class, when they hear about the Tao, earnestly carry it into practice. Scholars of the middle class, when they have heard about it, seem now to keep it and now to lose it. Scholars of the lowest class, when they have heard about it, laugh greatly at it. If it were not (thus) laughed at, it would not be fit to be the Tao." - Laozi Supposedly, if a person can understand Tao and become Tao, all mysteries are revealed.
