The symbol of the pyramid has been the symbol of the shaman for at least 300 years. The way of the shaman is the duality of the physical and spiritual. The balance of both in skill. Spiritual is everything outside the physical mind and body. The ancient skills were sacred skills because the art of them went beyond the physical skill and into a work of art. The difference is survival or thrive. Within the gift economy the arts were of the duality of both not just physical.
