Man must free himself from the weeds of ignorance, thorns of superstitions and thistles of imitations, that he may discover reality in the harvests of true knowledge. Otherwise the discovery of reality is impossible, contention and divergence of religious belief will always remain and mankind, like ferocious wolves will rage and attack each other in hatred and antagonism. We supplicate God that He may destroy the veils which limit our vision and that these becloudings which darken the way of the manifestation of the shining lights may be dispelled in order that the effulgent Sun of Reality may shine forth. We implore and invoke God, seeking His assistance and confirmation.
