"The higher world and the lower world are not separate, they are linked. That is why, when you have a very elevated, very spiritual wish, it can immediately provoke your lower nature and then arouse negative forces. Yes, those magnificent things you desire on high awaken contradictory forces and desires in the roots of your being! These tricks of the lower nature triumph with much greater difficulty in the disciple who is instructed and enlightened, because he knows that he must take precautions. At the same time he is building his inner temple, he positions around himself beings that watch over and protect him. In early freemasonry, whose philosophy is based on a true science, the mason is represented working with a trowel in one hand, and in the other a sword with which to defend himself. So, while the mason is busy building, he is also vigilant, he makes sure that in the cover of darkness certain enemies do not try to worm their way into his fortress."
