Ra never gave a checklist, and he never named 3-60 as a requirement. Where gates 60 and 3 do appear is inside the mutation itself, as the path through the Root that carries the change onward. Ra said "if it doesn't go through the 360, it doesn't bring the mutation to humanity." That is a description of a mechanism, not a qualification for parents. What he did say is that Raves are born to human parents and are not fertile themselves, and that much of his Rave picture is his own speculation. Nobody can look at two charts and tell you what kind of child will arrive. This is not a fact and not a medical statement, and nobody knows exactly how it will unfold.
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.
