"The immediate duty of everyone who knows about the Subtle World is to affirm the existence of this invisible but real world every time the opportunity presents itself. Some people may respond by getting angry, but it will give them an opportunity to think about reality. If research on human physiology were supplemented by the study of the Subtle World, which connects all the various conditions of existence, our world would at once enter into a distinctly new era. I can affirm that the commotion arising from the present turmoil has attained unprecedented proportions, because the bond between the worlds is totally ignored. Let nobody claim that he has not been warned in due time. Let the traveler not forget that he cannot return to the house that he left behind, that it is only by his own efforts that he can reach the Luminous City to which he has been summoned. Let the traveler remind everyone he meets at the crossroads that paths are irreversible."
