“There is a sacred science, and for thousands of years countless inquisitive people have sought in vain to penetrate its “secrets.” It is as if they attempted to dig a hole in the sea with an ax. The tool must be of the same nature as the objective to be worked upon. Spirit is found only with spirit, and esoterism is the spiritual aspect of the world, inaccessible to cerebral intelligence. Those who profess to reveal the esoterism of such teachings are charlatans.”
