Macrocosm and microcosm
（重定向自Macrocosmos）
Macrocosm and microcosm refers to a vision of cosmos where the part (microcosm) reflects the whole (macrocosm) and vice versa. It is a feature "present in all esoteric schools of thinking", according to scholar Pierre A. Riffard. It underlies practices such as astrology, alchemy and sacred geometry.
