Great to read your comments on David Hawkins - he is quite an amazing man - went to his lecture in Toronto a few months ago - very different lecture. I enjoyed P Vs F. The idea of calibrating products and people is fascinating. Did a course with a man who actually calibrates products before marketing them to his customers. His Flower Essences calibrate in the high 500's!. David has written another book which I have not read yet called 'The Eye of the I'. I find the Biokineseology and the calibration very powerful.
