Who is it who shouts loudest that there is no devil? Those who are most possessed by him. For the spirit whom we call Ahriman is enormously interested in having his existence denied by those who are most possessed by him. ”the common people never know the devil, even when they have caught him”. So that is a dreadful Maya, not to believe in Ahriman, for it means that he’s collared one most of all when one does not believe in him; in that case one gives him the greatest power over oneself.
It is wrong, therefore, to say that monists fight the devil when they rant and rave against him. No, a materialistic and monistic gathering where people rant and rave against the devil is liable to conjure up the devil. More than the witches of old do modern materialists call up the devil, much, much more so! That is the truth and the other is Maya.
So we must learn to judge things differently. Someone who goes to a monistic meeting with materialistic nuance is untruthful when he says that these people free humanity from the devil. He ought to say: I am now going to a meeting where the devil is called into human culture with all the powers that human beings have.
