If any of the mystical traditions appeal to you, please invest the small price to own this book. Clearly and concisely this small treasure reviews Patanjali's sutras. Alberto Villoldo makes them poetry to the soul and heart. Each sutra is given a few sentences so beautifully expressed that no more is necessary. To alleviate "disciple-quilt" he states so wonderfully to the advancing student on page xxvii "As Swami Venkatesananda said: "Renounce the self that does the renunciation". With so many New Age books leaving enthusiasts with an almost inability to speak a sentence without self-correction, "Yoga, Power, and Spirit" takes the true student to the heart of the ancient traditions and well beyond the superficial hype of the current, sometimes, very limiting explanation of the metaphysical and sacred. Simply Dr. Villoldo gives us an easily understood adjunct to other sound authors such as Paramahansa Yogananda, Wayne Dyer and Greg Braden. He is in that class!
