Lecture XI
You must understand how mediums get into this condition. Someone is a medium if his ego and astral body are pulled out of his physical and etheric bodies by an external force, and this was also what happened at the time of the Babylonian priests. However, another power sits in this ego and astral body as soon as they have been pulled out of the medium's physical and etheric body. Depending on whether the initiate who brings this about has good or bad intentions and belongs to the left or the right, this can be a good power or an evil one. Excellent things came to light in this way in ancient Babylonian times, but the problem was with what occurred when the medium returned to his physical body. You see, one cannot get by in the spiritual world with the logic and discrimination between lies and truth which one has in the physical world. It is a complete error to think that one can use the concepts of lies and truth which one rightly uses in the physical world, in the spiritual world. There is nothing there which one could distinguish in such a way. Some of the beings there are good and others are evil. One has to know them through themselves, and in fact, they tell one the kind of being they are. Even the evil ones are truthful in their own way. Of course this is difficult to understand, just as it is difficult to understand what happens in the spiritual world as soon as one enters it. For instance, here in the physical world we say that a straight line is the shortest path between two points. However, in the spiritual world it is the longest distance between two points and every other one is shorter. So that we cannot apply anything which we have to use in the physical world to the spiritual world.
