...and take some of the other advice with a grain of salt.
The woman who wrote this book was one of Yogi Bhajan's earliest students - I believe that she is in her sixties or seventies. I mention this because I would advise anyone to read this book the same way they take advice from an older person of a different generation...
I started reading the book in 1999, after I had done a little bit of Kundalini - and I will admit that I got turned off - by the advice to take cold showers, some of Yogi Bhjan's quotes about women etc., etc. Then I promptly quit doing yoga, bought a house (a fixer-upper) and got a stressful job. Almost exactly one year later I realized that I needed to calm my mind and my body because I was a wreck. I took a few Kundalini classes, but really needed something that I could practice at home. So I dug out this book - and went straight to the exercises. Flow of Eternal power presents the exercises in sets which you can make last from 20 minutes to an hour and a half. I bought a digital kitchen timer so that I could hold the poses for a the prescribed period of time and off I went. Well, THE KUNDALINI EXERCISES MADE A BIG DIFFERENCE AND I STARTED TO FEEL 100% BETTER.
So, my advice is take what is offered and use it to your benefit - leave out what you don't feel comfortable with (actually the cold showers can be pretty invigorating and the advice about caring for oneself is pretty cool too).
so i heard about kundalini yoga from a friend in my composition class... i'd been practicing meditation for about a year and a half at this time and was looking for something new... I didn't like the life-denying view that some of the schools seemed to take, nor their meditations.
kundalini yoga, as i was informed, and later read, was meant to let you live a life in the body to its fullest potential, using everything, all situations, to your advantage. that's what attracted me to it. that's what attracted me to tantra as a whole.
so i got this book, read it, and was rather disappointed to tell you the truth. the exercises, i will admit, are well detailed. the philosophy behind kunalini yoga is laid out well. all of the mantras are there. but still, something is lacking. other reviewers speak of her free-flowing style, and, while it may seem free-flowing, it clearly isn't. It's nothing at all like reading the works of enlightened masters. rather than clarifying, in my opinion some of the more esoteric aspects of the yoga, she seems to muddy them up a bit. this, perhaps, is because she lacks the depth of insight of someone who has arrived and, therefore, the information she gives on various aspects of kundalini yoga are things that she has read or heard, not things she expereinced firsthand.
to sum it all up, i certainly wouldn't recommend this book. it is, i will admit, good for the body, as the exercises are well-detailed and laid out in an easy-to-read manner. for the mind, though, it is definitely lacking. i would recommend a book by osho called "the book of secrets" for actual meditation methods. combining this one and that could benifit one greatly.
