Tao te ching - Meaning of a quote (in description)?

I'm no expert on this at all. In fact, I only got a little exposure to it through studying the works of Carl Jung, and that was a long time ago. But it seems clear to me that the theme that unites all the statements in that passage is: inner peace (or "contentment"). I would venture that he is also saying that while inner peace is the greatest value (or certainly a very great value), therefore whatever threatens that is the worst disaster -- the greater the value of anything, the greater is the catastrophe if it should be destroyed. He is also saying that worldly, materialistic pursuits ("getting") are the greatest threat to inner peace. Therefore to encourage worldly ambition is an attitude that causes (or we might say, should cause) the greatest guilt, and so forth. When you are sufficient in inner peace (as opposed to the false feeling of sufficiency that one gains from material possessions and acquisitions) then are you truly sufficient, and sufficient in an enduring and unchanging way. I think in the way in which genuinely true things were regarded as eternal, and eternal things true, and that the more obviously temporary a thing was, like material ambition, the more false it really was, was perhaps one of the few areas in which Eastern and Western philosophy were very much alike.
