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