Lecture Four

We shall now have to consider a correspondence that is found to exist, an absolute correspondence, in respect of Number. I have already often drawn your attention to this correspondence between Man and the world in which he evolves. I have pointed to the fact that Man, in his rhythm of breathing—18 per minute—manifests something that is in remarkable accord with other processes of the Universe. We make 18 respirations per minute, which gives when calculated for the day, 25,920 respirations. And we arrive at the same number when we calculate how many days are contained in a normal life term of 72 years. That also gives about 25,920 days; so that something may be said to exhale our astral body and Ego, on falling asleep and inhale them again upon waking—always in conformity with the same number rhythm.
