If you're really interested in knowing something about the Kundalini process, this is a book you can't afford to miss. I haven't come across another book even remotely close to the detail provided here. The author shares his experiences, both, after his abortive kundalini arousal and then kundalini activation through the grace of his guru leading him to self-realisation / enlightenment. This book is not for the faint-hearted. It has extremely painful and blissful, but real experiences of the author relating to his kundalini arousal. Many of these experiences will be hard to comprehend for most people. I read this book 23 years ago and even today have a strong imprint of the goosebumps I experienced whilst reading it.
