A man told me not long ago that he got tired out for the day in walking to his office with a friend, because they both talked so intensely. And that is not an unusual experience. This chronic state of strain and excitement in everyday matters makes a mental atmosphere which is akin to what the material atmosphere would be if we were persistently kicking up a dust in the road every step we took. Every one seems to be stirring up his own especial and peculiar dust and adding it to every one else's especial and peculiar dust. We are all mentally, morally and spiritually sneezing or choking with our own dust and the dust of other people. How is it possible for us to get any clear, all-round view of life so long as the dust stirring habit is on us? So far from being able to enlarge our horizon, we can get no horizon at all, and so no perspective until this human dust is laid. And there is just this one thing about it, that is a delight to think of: When we know how to live so that our own dust is laid, that very habit of life keeps us clear from the dust of other people. Not only that, but when we are free from dust ourselves, the dust that the other men are stirring up about us does not interfere with our view of them. 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. You never had found and you did not understand quiet.
