Man lives in two kinds of worlds, which he has to unite in himself. On the one hand he is the cornerstone of the outer, material creation, in which he is called the crown of creation and he is praised as such. On the other hand, he is the starting point of the pure spiritual world, which with him has reached the first stage of complete free self-awareness. So, on the one hand he is the beginning of chain and, on the other hand, the end of a chain, and he has to find in himself (for that purpose life was given and its free development) the missing link with which he can make those two chains as one.
This is “the most unlikely book ever”!
