Planetary Evolution and the Evolution of Humanity
The third and most significant thing is when the human being not only begins to become master over the forces of his etheric body, but when he begins to work down into the physical body. It might seem as though the work of the I on the physical body is the basest; but it is in fact the highest. And the work on the physical body is more difficult than the work on the etheric body. When a person consciously begins to work on mastering the forces that work in the physical body through the I, then something else occurs to him. What works in the physical body are the same forces that work in the cosmos. When a person learns to control the forces of his blood and his breathing, he learns the magic of the cosmos. Then what he can do flows out of his physical body and into the universe, and that is a real, true work that can only begin when a person has reached a certain level of work on the etheric body. And because we begin with the regulation of our neighbor, with the regulation of breathing, the name breathing is also taken from 'Atma'. The more a person transforms in his inner physical nature, the more there is of the 'spirit man', of 'Atma'; there is a part of spirit matter in him that has been transformed.
