"The only unchanging rules you must conscientiously obey are that you must always faithfully and without deviation follow the instructions accompanying the exercises and always keep your mind wholly concentrated on the purpose of the exercises as you perform them. This is vitally important in order for you to gain the results sought, otherwise, there would be no valid reason for your interest in Contrology... The benefits of Contrology depend solely upon your performing of the exercises exactly according to instructions- and not otherwise." -J.H.P.
