What is what does as above so below mean?

As Above, So Below is a phrase commonly associated with the concept of hermeticism, which is a philosophical and religious tradition that dates back to ancient Greece. It's a shorthand for a belief in the correspondences between the physical and spiritual worlds. The phrase suggests that what happens on a higher, metaphysical level also manifests on a more earthbound realm, suggesting a connection between the sky and the earth, the macrocosm and the microcosm, and the spiritual and the physical. The idea is that everything is connected and that what happens in one realm affects or reflects what happens in another. In essence, it's a reminder that the universe is a mirror of itself, with everything being tied together in some form or another.
