Never take over the world to tamper with it. Those who want to tamper with it are not fit to take over the world.
Virtue in its grandest aspect is neither more nor less than following reason.
He who does not trust enough will not be trusted.
Attain utmost emptiness. Abide in steadfast stillness.
The highest truth cannot be put into words.
A good door needs no lock, still it can't be opened.
