128. The Introduction of Our vade maecum

When one has experienced the strengthened thinking that leads to the etheric world, one can suppress it through the inner power of the soul. In the normal process of life, sleep must occur through such an inner process. However, one can also train oneself not to let the soul fall asleep when suppressing the intensified thinking. The consciousness then remains awake, even though no more impressions come from outside. A real spiritual world then reveals itself to this consciousness. A spiritual world is added to the ordinary world. In this spiritual world one recognizes a third human organization, a kind of “third person”. One can call it the astral organization.
