13. Morality in the Light of Spiritual Research

But now it immediately becomes apparent when spiritual science wants to ascend to the spiritual sources of existence, that then, in a certain way, when the human soul wants to become a spiritual researcher, it must develop three things. This threefold nature has been presented in the course of these winter lectures as the three stages of supersensible knowledge. First, we have mentioned what we call imaginative knowledge, that is, the knowledge that arises in the human soul when it has completely freed itself from all sense observation and all intellectual activity that is bound to the instrument of the brain. When the soul has reached the point where it feels a world of images emerging from its depths, then, with further training of the spiritual researcher, these images will become images of the real spiritual realities that exist behind the external sense world. Imaginary knowledge is the first. These stages of supersensible knowledge are also discussed in the book “How to Know Higher Worlds.”
