The Human Design System channeled by Ra Uru Hu in 1987 was a breakthrough in knowledge that aimed at synthesizing ancient wisdom tools into a modern tool for self-knowledge. When Ra Uru Hu was given the information he was given the body graph and its channels and hexagram correspondences as well as the geometric and specifications for the body graph.
As Ra worked with the materials attempting to understand the knowledge associated with the structure he was given he came up with his own interpretation of the information. The evolution of Human Design was critical in bringing new knowledge of how the systems it included in the body graph could be synthesized. However, Ra was a messenger not a theoretician or a social scientist and he knew that he needed more scientific knowledge to make the information he was given longevity.
The Four Worlds
Ancient Wisdom teaches that we live in a multidimensional universe and function in four worlds accessible to our consciousness as well as other dimensional realities that are beyond the veil of general awareness.
In recent times, more people are talking about and recognizing that consciousness is not limited to the waking world and that many individuals function in dimensions of time and space that cannot be easily quantified.
As a clinical psychologist, I have worked with dreams and other dimensional awareness throughout my practice and have documented the worlds in the Beyond Human Design Charts statistically as well as clinically.
In short, there are many layers of functioning, but those who only believe in the physical and personality expressions of being are limited and missing out on learning from the other realities they’re actually operating in unconsciously.
