These lines mark the point at which the combined effort of stillness and understanding has been sustained for so long that we undergo the final transformation, into a being who can serve all worlds. At this point we will have four distinct parts, or bodies.
In a way, we already possess the first part of an angel, and we always have. It is the simple fact that we are not what we are: you are not the person they give that word, your name. Rather, the name—the seed picture—came first, and then made you you. Since you are not you any other way, you are available to become something else—an angel. And you always have been. This is your first body.
When we grasp that the way we look—our physical appearance— is also available in the same way, we begin the hard work of collecting enough seeds to change the actual physical elements of our body into those of the angel.
