Not all the chains are bad and not all the freedoms are good!
Man sometimes needs only stillness, just stillness!
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.
Heraclitus says you cannot step into the same river twice. We can also say that the same river cannot touch us twice!
When the sun is setting, leave whatever you are doing and watch it.
Our chair will remain empty one day, but our ideas will continue to sit on that chair! However in the very distant future, there will remain neither chair nor ideas! All will disappear!
