hDer Weg ist das Ziel
(The path is the destination /the destination is not
important, but the path that leads there)
(Knowledge cannot be stolen by thieves,
It cannot be forcibly snatched by kings,
It cannot be devided among brothers,
It does not cause a load on shoulders,
If spent or shared, it indeed always keeps on growing.
The wealth of knowledge... is the most superior wealth of all!)
