We see the men through their dust and we see how the dust with which they are surrounding themselves befogs them and impedes their progress.

From the place of no dust you can distinguish dust and see through it.

From the place of dust you cannot distinguish anything clearly.

Therefore, if one wishes to learn the standards of living according to plain common sense, for body, mind, and spirit, and to apply the principles of such standards practically to their every-day life, the first absolute necessity is to get quiet and to stay quiet long enough to lay the dust.
You may know the laws of right eating, of right breathing, of exercise, and rest--but in this dust of excitement in daily life such knowledge helps one very little.

You constantly forget, and forget, and forget.
Or, if in a moment of forced acknowledgment to the need of better living, you make up your mind that you will live according to sensible laws of hygiene, you go along pretty well for a few weeks, perhaps even months, and then as you feel better physically, you get whirled off into the excitement again, and before you know it you are in the dust with the rest of the world, and all because you had no background for your good resolutions.
