The book "Eye of Rebirth" was written by P. Calder before World War II. It is a story about an amazing discovery of a source of inexhaustible youth, made by the British Army colonel Sir Henry Bradford in the mountains of Tibet.
The six simple initial rejuvenation exercises described in this book proved very effective, and the book is even recommended as a study manual by many esoteric (and not only) schools in the country. The advice given in this “talking” book is available to practically anyone—from a businessman to a pensioner. "Eye of Rebirth" is not only a description of the secret practice of Tibetan lamas in the not-so-distant past, which leads to the turning of the inner flow of time, the development of personal power, and the preservation and restoration of health and the youth of the body—but in A. Sider’s retelling, the book looks like an engrossing work of fiction.
