A term which is particularly significant within esoteric astrology and as an explanatory model for the concept of analogy. According to this idea, the wider macrocosmic universe is reflected in the microcosmic world - including human beings. Everything that happens in one dimension has its correspondence in the other. Astrology is therefore seen as a tool to decipher the cosmic plan in the human sphere.
The concept of a relationship between the micro- and macrocosm is very similar to the idea behind astrology itself but also appears in other spiritual teachings and is not restricted to astronomical observations. The first person associated with the idea is the legendary figure of Hermes Trismegistos.
