No. Ra himself called the cosmology important but not necessarily practical knowledge, and said mythology still belongs to any complete knowledge. He called the Global Cycles cosmology, not practical knowledge. The practical part of Human Design is your chart, your Type, your Strategy and your Authority. He also said that after 2027 studying Human Design is not the point, living your design is. You can live your design well without ever reading a word about Global Cycles.
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.
