Penney Peirce, author of Freqency, at Powell's Books on Hawthorne April 30, 2009

Because science has long taught us to rely on what we can see and touch, we often don't notice that our spirit, thoughts, emotions, and body are all made of energy. In Frequency (Beyond Words), Penney Peirce shows you how to feel your personal vibration and work intentionally with energy to transform your life.
