Lecture X
So let us do some more arithmetic to see how we relate to the world with our breathing, how we relate to the course of a macrocosmic day. We can figure it out in this way: Start from one day; in a year there are 360 days. (It can be approximate.) Now take a human life (again approximate) of seventy-two years, the so-called human life span. And we get 25,920 days. So we have a life of seventy-two years as the normal rhythm into which a human being is placed in this world, and we find it is the same rhythm as that of the Platonic sun year.
