A place where there is an intensity of beneficial energy and a meeting point of yang and yin earth energies. Power centres are associated with blind springs that have at least one energy ley crossing them and are found at most ancient sacred sites, frequently accompanied by radials and/or a geospiral. However, they can also be found elsewhere. Power centres are generally considered to be places suitable for spiritual enlightenment and healing. Dowsers using a sleeved L-rod have noted that when directly over a power centre the rod will rotate through 360 degrees.
