The Guardian of the Threshold
There are esotericists who believe that they do not want to concern themselves with becoming clairvoyant because there are so many difficulties and dangers associated with it. They recoil. Yes, it is true, there are countless dangers and difficulties that every esotericist encounters before he becomes clairvoyant, and also after he has received [clairvoyance]. Lucifer and Ahriman are always trying to get power over people, but never as strongly (powerfully) as after the attainment of higher knowledge. One must not blind oneself to this and for this reason refrain from doing everything to attain this ability; that is the absolute duty of an esoteric. The development of humanity has now reached the point where basically every person should consciously strive to go the occult way. The spiritual world is now so close to human consciousness, if only people would make an effort to remove the last veil. But if they fail to do so, the development will fail and people will be drowned in everything that pulls them away from the spiritual, in materialism, worship of mammon, self-interest and so on. Therefore, a small number of people must in any case absorb spiritual science, the spiritual, and follow the esoteric path.
