"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." [R. A. Schwaller de Lubicz]
"The spiritual temple is locked with many keys and those who are vain enough to believe that they can invade it by their own power and without being shown the way by the light of wisdom, will storm against it in vain. Wisdom is not created by man; it must come to him and cannot be purchased for money nor coaxed with promises. It comes to those whose minds are pure and whose hearts are open to receive it." [Paracelsus]
