In medieval Europe, the guilds were mystery schools. The cathedrals that they built reflected the mysteries of an inner law of the soul in architecture, in their design, far beyond the comprehension of medieval man. The artisans were skilled in raising the consciousness of those who entered these cathedrals by building around them a structure that reflected the inner geometry of divinity that is God. Many of the secrets of the temple of Solomon and of the Great Pyramid are evidenced in the teachings of these mystery schools. The romances of King Arthur and his Knights of the Round Table are also the reports of one of the mystery schools of the Brotherhood.
