We do not found ourselves on faith alone, but on a great ground of knowledge which we have been developing and testing all our lives. I think I can say that I have been testing day and night for years upon years more scrupulously than any scientist his theory or his method on the physical plane. That is why I am not alarmed by the aspect of the world around me or disconcerted by the often successful fury of the adverse Forces who increase in their rage as the Light comes nearer and nearer to the field of earth and Matter.
