The greatest tragedy that can befall a person is the atrophy of his mind.

Those that think that wealth is the proper thing for them cannot give up their revenues; those that seek distinction cannot give up the thought of fame; those that cleave to power cannot give the handle of it to others. While they hold their grasp of those things, they are afraid of losing them. When they let them go, they are grieved and they will not look at a single example, from which they might perceive the folly of their restless pursuits - such men are under the doom of heaven.

As regards the quietude of the sage, he is not quiet because quietness is said to be good. He is quiet because the multitude of things cannot disturb his quietude. When water is still, one's beard and eyelashes are reflected in it. A skilled carpenter uses it in a level to obtain a measurement. If still water is so clear, how much more are the mental faculties! The mind of the sage is the mirror of heaven and earth in which all things are reflected.

When he tries to extend his power over objects, those objects gain control of him. He who is controlled by objects loses possession of his inner self... Prisoners in the world of object, they have no choice but to submit to the demands of matter! They are pressed down and crushed by external forces: fashion, the market, events, public opinion. Never in a whole lifetime do they recover their right mind!... What a pity!

Birth is not a beginning; death is not an end. There is existence without limitation; there is continuity without a starting point.
