Third Lecture

There are now people who begin to apply to themselves the rules of my writing “How to Know Higher Worlds,” the rules that are called the rules of occult development. They may apply them for a very long time; but then, after years, they come and say, “I have practiced over and over again, I have done all kinds of exercises; I see nothing, I hear nothing of the spiritual world. My sense for the spiritual world does not want to open up. Perhaps what these people say is completely wrong; it can be completely wrong. The people in question may have long since found entry into the spiritual world and may have perceptions in the spiritual world. But these perceptions disappear the moment they are made, because these perceptions cannot be incorporated into the physical memory. The fact that one can know something from one's spiritual experiences depends on something quite different from memory. And I would now like to make clear to you what it depends on.
