"The circles containing the sensitized disks - both polar and depolar - are in sympathetic relation to the polar negative circuits of the earth, and in a condition to be brought into action by the negative transmitter. The sympathetic conditions of the polar and depolar field of the circuits remain latent until the transmitter is associated and the introductory impulse given. Then conditions assert themselves which demonstrate the wonderful power of sympathetic action in abeyance to the laws by which they are governed." [The Operation of the Vibratory Circuit]
