Too much of fluoride in your tap water, tooth paste, etc might be very negative especially for Kundalini practitioners. Most of the fluoride calcifies at the Pineal Gland thus reducing the 'Unarvu' or awareness. Studies done by British scientist Jennifer Luke in the 90"s verify these negative effects in the human body. Pls google Jennifer Luke for more details. One way of de-calcifying the fluoride from the Pineal would be to stare at the early morning sun with eyes closed and absorb the suns rays thru your 3rd Eye. A few minutes would be enough. No harm in doing everyday. It would be a good idea to drink RO water and use non-fluoridated tooth paste. Santhosham.
