The world does not yield to changing. By its very nature it is painful and transient. See it as it is and divest yourself of all desire and fear. When the world does not hold and bind you, it becomes an abode of joy and beauty. You can be happy in the world only when you are free of it.
You can become a night watchman and live happily. It is what you are inwardly that matters. Your inner peace and joy you have to earn. It is much more difficult than earning money. No university can teach you to be yourself.
Multiplicity without strife is joy.
