Lecture II
Therefore we must make the line of the loop, the lemniscate, open on one side, closed on the other, and draw it like this—here the line of the loop is closed and here it goes out into infinity. It is the same line that I drew there, only here the arm goes out at this end into infinity (see diagram 4 of lemniscate open to the outside). What I have here drawn as an open lemniscate, as an open loop, is not just something thought out, but something you can actually look upon as flashing in and out of a gentle, very slow movement as the expression of man's relation to the universe. The currents of the universe continually approach man; he draws them towards him, they become intermingled in his vicinity and proceed outward again. Thus this kind of thing streams towards man, interweaves and then goes out again; man is permeated by these currents belonging to the universe, which stop short in front of him.
