T C Lethbridge – The Power of the Pendulum
[The ability to have a spiritual experience], whatever it may be, is generally known as 'psi' and a person's psi count can be worked out with the pendulum set at 9 1/2 inches. In practice it is found that a person whose number of gyrations at 9 ½ inches is under ten, will have some difficulty in using the pendulum or divining rod; with repeated experiments the number can apparently be steadily increased.
Whether we can equate psi with intuition is not certain; but it seems probable that intuition is a facet of the larger psi.
A certain number of people have no psi count but instead react to a minus rating of 29 1/2 inches. As far as we can judge at present this minus reading is combined with, or due to, some nervous disability.
