In Ra's cosmology it is the last major biological mutation, but not a staircase to perfection. He said an eleven-centered being will never come: Raves and humans both stay in the nine-centered body. He also said humans are not a stage on the way to becoming Raves. Beyond that he mentioned, once, a later form that would no longer be biological, far outside anything that concerns us. None of this touches your own life today, and he called large parts of it speculation.
This is not a fact, not medical advice and not a promise of healing. It is part of the cosmology Ra Uru Hu, who founded Human Design, left behind, and nobody knows exactly how it will unfold.
