"The only thing to do with good advice is to pass it on. It is never of any use to oneself."

You see, in life, lots of people know what to do, but few people actually do what they know. Knowing is not enough! You must take action.

The meaning of life is contained in every single expression of life. It is present in the infinity of forms and phenomena that exist in all of creation.

正该来时，先生（老子）应时来到这世间；正该去时，先生顺时离开这世间。安于时势，顺应自然规律，哀乐就不能进入心中。
