So you see, our life on earth lies between these two things—our own breathing and the cosmic year. Everything that is of any importance for the human ego is ruled by the breath. And the life of our physical body lies within those colossal processes that are ruled by the rhythm of 25,920 years. The activity that takes place in our physical body in accordance with its laws is connected with the large rhythm of the Platonic year in the same way that our ego activity is connected with the rhythm of our breathing. Human life lies in between those two rhythms. Our human life is also enclosed within physical-etheric body and astral body-ego. From a certain point of view we can say that human life on earth lies between physical body-etheric body and astral body-ego; from another point of view, from the divine, cosmic aspect, we can say human life on earth lies between a day's breathing and the Platonic year. A day's breathing is in this sense a totality; it relates to our whole human life.
