The first book is "Hands of Light" by Barbara Brennen, in this book she says that fluorescent light bulbs induce a beat frequency in the human aura which can be detrimental to health. Indeed older types of fluorescent tubes do cause some people problems due to the 50/60 Hz flicker. But what she doesn't say is whether this applies to the newer type of compact fluorescent light bulbs which have an electronic ballast and switch at 20,000 Hz or even higher. For those interested the best type of bulbs are the halogen variety.
The second book is "Power Vs Force" by David Hawkins. David Hawkins is a great believer in Applied Kinesiology muscle testing, one such method is to place an object over a subjects solar plexus, the subject will go momentarily weak if the object is detrimental to life. The exact procedure is too long to describe here but can be found on the Internet for those interested. Anyway, as you guessed a fluorescent light bulb causes the subject to go weak.
Before knowing the above I had CFLs throughout my house but have since changed back to incandescent bulbs. But this really annoys me as CFLs seem the "right thing to do". Also incandescent bulbs are becoming harder to buy, low energy bulbs are, for obvious reasons, being pushed hard.
So what are other peoples thoughts here on fluorescent light bulbs?
BTW: I would highly recommend both Barbara Brennen's books for anyone suffering long term health problems, very interesting.
