Lao-Tse sagt: Nichtstun ist besser, als mit viel Mühe nichts zu schaffen.
Und er sagt auch: Ich habe drei Schätze, die ich hüte und hege. 
Der eine ist die Liebe, der zweite ist die Genügsamkeit, der dritte ist die 
Demut. 
Nur der Liebende ist mutig, nur der Genügsame ist großzügig, nur der Demütige 
ist fähig zu herrschen.
