Many people are now keen on eastern health systems - Indian yoga, Chinese qigong, Tibetan traditional medicine - in conditions where people are largely left to themselves, the popularity of such “overseas” techniques is growing. But the experience of a healthy lifestyle of the Russian people is in no way inferior to that of the Indian, Chinese, Japanese or any other. Unfortunately, many traditions of folk health have been forgotten in our country, or at best, half-forgotten. Official science is beginning to study them.  Followers of Porfiry Ivanov call his system “Child” - that’s what the folk sage called his commandments. This is a fairly accurate name for the system—some even use the lofty word “teaching.” Well, what are his commandments, what are his rules of natural healing, the reader will learn from the proposed book. Its author is one of P. Ivanov’s most faithful students, and the “Detka” system became a way of life for him.
