The Teacher says: I discovered this while trying to discover the scheme of things, item by item.

I tried to understand, examine, and comprehend the role of wisdom in the scheme of things, and to understand the stupidity of wickedness and the insanity of folly.

Whatever you find to do with your hands, do it with all your might, because there is neither work nor planning nor knowledge nor wisdom in the grave, the place where you will eventually go.
