It is a great pity that the mechanical and artificial life that we live in this world today is depriving us of that natural experience of deep sleep. Our first fault is that we congregate and live in one city all crowded together. Besides there are motorcars, trains, and tramways, and houses of twenty stories shaking every moment of the day and night. Every vehicle is shaking; and we are a race at the present time which is unaware of the comfort, the bliss, and the peace known to the ancient ones who lived simply with nature, far from our mechanical and artificial life. We are so far removed from the old ways that it has become our habit. We do not know any other comfort except the comfort we can experience in the kind of life we live; but at the same time this shows that the soul is capable of attaining to greater comfort, pleasure, and joy, to greater peace, rest, and bliss only by living naturally.
