About the book: 2000 / The topic of gaining immortality has worried the most inquisitive minds of humanity for many millennia. And in our time, many are looking for recipes for eternal life. The book outlines a fail-safe (which is confirmed by those who themselves have achieved immortality) method of gaining eternal life, offered to the reader within the Christian tradition, and based on practices known to our distant Indo-Aryans forefathers. The key to immortality and power is mastering an alternative method of breathing - internal endogenous breathing. At the same time, the author convincingly shows that Christianity was originally a revival of the ancient science of immortality, the main provisions of which in our time are mostly forgotten or lost.
