The sacred geometry of the pyramids may be more than architectural brilliance. Could it be evidence of ancient technology embedded in human biology? In his search for musical and mathematical clues in Egypt, Robert Edward Grant uncovers stunning harmonic ratios within a ruined pyramid northwest of Giza. These same proportions appear in Da Vinci’s Vitruvian Man, the Mona Lisa, the third eye, and the Philosopher’s Stone. Grant’s findings reveal a hidden blueprint that may hold the key to activating a crystalline structure, expanding perception, and reshaping our experience of time.
