'The Interconnectedness of All Things – From the Perpetual Choirs of Britain to the present day' was written by John Gibson-Forty. Unfortunately, John had a massive stroke shortly after publication, and as his publisher, Trish Mills has been doing talks on his behalf.
In a nutshell, the Perpetual Choirs were three choirs, probably comprised of early monks, saints or Druids, who maintained ceaseless chanting on a rolling rota basis, 24/7, for the ongoing enchantment of Britain. Their area of influence dowsed as being a ten-sided Decagon centred on Whiteleaved Oak and Ragged Stone Hill in the Malvern Hills.
During his research, John inadvertently discovered that energy lines are constantly increasing and decreasing in width. He eventually figured out why, and Trish reveals the secret to the mystery.
Trish, Chairman of Slimbridge Dowsing Group, has presented this talk many times; the Hundredth Monkey effect has kicked in (tipping point) and today folks are singing the lines - annually, worldwide - in the hope of bringing back some of the enchantment.
