"Why spend money on what is not bread, and your labor on what does not satisfy? Listen, listen
It is possible to seek value where there is none. Most people live no longer than 70 or 80 years. By existing they are using up strength, energy and opportunity; there's too little to waste. It makes sense to maximize satisfaction. A well known advertisement has the line: "Oils ain't oils." Isaiah says, "Bread ain't bread." There is that which seems to be just what we want--but it isn't. Real satisfactions are drawn from the spiritual realm. It is in the region of the 'soul' that mankind finds that which alone gives peace and joy.
