When the desire ain't on me I don't need help. When it is on me I don't want any. See? Like the old fellah that never mended his roof. Said on a wet day he couldn't do it and on a dry day it was as good as anybody's.
For if you know what you want, and will be content with it, you can be trusted. But if you do not know, your desires are limitless and no one can tell how to deal with you. Nothing satisfies an individual incapable of enjoyment.
It (Tao) is eternally without desire. So, it can be called small. All things return to it, although it does not make itself their ruler. So, it can be called great.
