In the enemy's territory, be as silent as the owl's wings; in friend's territory, be as cheerful as the nightingale's songs.

Sometimes principles must be quitted without blinking en eye to discover the new paths!

No hero is a hero if he ever killed someone! Only the man who has not any blood in his hand can be a real hero! The honour of being a hero belongs exclusively to the peaceful people!

The stupid thief wears the sheep bell around his neck! Such stupidity of the bad is always good for the society!

Sometimes it is not wise to make a second plan; it diminishes the power of the first plan! In risky paths, make only one plan; this will increase the possibility of success! On the edge of a precipice, if your second plan is a parachute on your back, your possibility of falling will increase! When you have nothing to trust, you will be safer, because you have no right to make any mistake!

There is nothing invisible in this universe! There is only our lack of eyesight!

Earthworms cannot be painters. Those who live in the darkness can never perceive and appreciate the beauties of the light!
