To use what has a boundary to pursue what is limitless is dangerous; with this knowledge, if we still go after knowledge, we will run into trouble. Do not do what is good in order to gain praise. If you do what is bad be sure to avoid the punishment. Follow the Middle Course, for this is the way to keep yourself together, to sustain your life, to care for your parents and to live for many years.
ZhuangziThose who follow the Tao are of clear mind. They do not load their mind with anxieties and are flexible in their adjustment to external conditions.
ZhuangziWhen 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!
Zhuangzi
