The knowledge of the hidden life force Kundalini, which lies within waiting for its awakening, is one of the best-kept secrets of yoga. The great sages of the East always passed these teachings on only to a few chosen students, whom they had convinced of their character suitability over many years. This book presents, for the first time, an insider's account in which a Westerner documents his long-term training with a great Kundalini master. Never before has the mysterious process of the ascent of Kundalini through the chakras been described so openly and in such detail in the West as in this masterpiece. It reveals for the first time the innermost knowledge of the ancient tantric tradition and demonstrates how profoundly nearly all psychological processes of human beings are connected in one way or another to the power of Kundalini.
