Ancient Symbols Simplified.
A crop circle appeared in Cley Hill Wiltshire England on July 28, 2017 (colour photo). It's similarity to Metatron's Cube struck me. See the black and white photo below.
Metatron's Cube is a sacred geometric symbol to open our consciousness to higher levels of existence and bring inner peace. Metatron is a celestial scribe referred to in mystic Kabbalistic texts.
