How Magic Works: The Law of Correspondence — As Above, So Below

By Hank, Graduate Gemologist & Professional Spell Caster | Crystal Conjure Magic

How Magic Works · Part 1 of 7 — the real principles behind every spell, one law at a time.

Look at the sun and you already know its nature, even if you’ve never put it in words: blazing, central, the thing everything turns toward, the source of warmth and life and rule. Hold that nature in mind, and then notice where else it appears.

In gold — the one metal that never tarnishes, the metal we have always made crowns from. In the lion, the beast we call king. In the heart, the organ at our center that every other part depends on, the one we point to when we mean the core of a person. In high noon, the sun at its height. In the color gold itself. In the heliotrope, the flower the ancients named for the way it turns all day to follow the light.

A star, a metal, a beast, an organ, an hour, a color, a flower — seven unrelated things, and one single nature running through every one of them. They are kin. Not because they resemble each other — gold looks nothing like a lion — but because they are the same nature wearing seven faces.

That is the oldest idea in magic, and the ground everything else in it stands on. The old practitioners called it the Law of Correspondence, and it says something simple and astonishing: the world rhymes with itself. The same essential natures recur at every level of it — in the sky, in the ground, in the body — binding things into families. Learn the nature of one, and you have already met its relatives everywhere.

Once you have the key, the families turn up everywhere. The Moon has its own: silver, which brightens and darkens like the moon’s own changing face; the pearl, and selenite — the pale stone whose name means moonstone; the creatures of night and water; the tides; and the inward, dreaming, changeable part of us that rises and ebbs on a rhythm of its own. Where the sun’s family is bold and bright and constant, the moon’s is cool and shifting and deep. Each nature gathers its kin across every level of the world — the heavens, the metals and stones, the plants, the animals, the body, even the hours and the seasons — until the whole of creation is sorted, not into a heap of separate things, but into a web of related ones.¹

You may know the law’s most famous line — as above, so below. It names one edge of this truth: that the great patterns overhead are answered in the small things down here, and in us. We carry the sun’s day and the moon’s month in our own bodies; we are, as the phrase goes, made of the same stuff as the stars.² True — but it is a single strand of something far larger. The wonder isn’t only that we echo the sky. It’s that the whole world is built this way, level answering to level, nature calling to nature, all the way down.

People found this everywhere, in every age. The Chinese sorted the whole cosmos into five natures — wood, fire, earth, metal, water — each with its own season, color, direction, and organ of the body, all moving one another by a kind of resonance, the way one struck string sets another humming across the room.³ In India they put it in a single line: whatever is in you is also in the universe.⁴ These were people who studied the world with great care and great patience, and what they found, again and again, was not a warehouse of separate things but a world of families — the same handful of deep natures, repeating.

And here is why any of this matters for a spell. If the world really is sorted this way — if a thing and its far-off kin share one nature — then they are not strangers to each other. Reach one, and you lean on the rest. This is the quiet engine under every casting. A caster who wants to call on the sun’s nature — its warmth, its authority, its life returning — does not need the sun itself. The caster can work with gold, with the heliotrope, with the right color and herb, because each of these is that same nature in a form a human hand can hold. The spell gathers a family together and speaks to all of it at once. Everything else in this series — the way a likeness can stand for a thing, the way a name can reach a person, the way the right materials carry an intention — is a way of working within these families. This first law is the one that lays them out: it tells you what is kin to what, so you know which thread to pull.

So the pull you feel looking up at the stars is not a child’s notion to be outgrown. It is a true reading of the world. You are not a stranger set down among dead things — you belong to families that run from the sky to the stone to your own beating heart, the same few deep natures echoing through all of it. That is the Law of Correspondence. Learning to recognize those natures, and in time to work with them, is where magic begins.

Frequently Asked Questions

What is the Law of Correspondence?

The principle that the world rhymes with itself: the same essential natures recur at every level — in the sky, in minerals and plants, in animals, in the human body — so that things sharing a nature (the sun, gold, the lion, the heart) are kin. It’s the oldest idea in magic and the foundation the rest is built on.

What does “as above, so below” mean?

That the great patterns of the heavens are answered in the small things of earth, and in us. It’s the most famous line of the law — but one strand of it, not the whole. The phrase comes from an old text called the Emerald Tablet.²

Isn’t this just “everything is connected”?

It’s more precise, and more useful. Not everything connects to everything; rather, things that share a nature are kin across every level of the world — real families, not a vague web.

Why is it the first law of magic?

Because a spell reaches a thing’s whole family through any one of its members, since they share a nature. Every other law is a way of working within these families — this first one tells you which things are kin, so you know what to work with.

Sources

1. The planetary “families” — the Sun’s gold, lion, and heart; the Moon’s silver, pearl, and selenite — are set out most fully in Cornelius Agrippa, Three Books of Occult Philosophy (1533), Book I. The old sources overlap and disagree, so the clean one-stone-one-purpose charts online are a modern tidying of something older and richer.
2. “As above, so below” comes from the Emerald Tablet (Tabula Smaragdina); its oldest surviving version is an Arabic text of about the late 8th–9th century, later brought to Europe in Latin — there is no ancient-Egyptian original. “Made of the same stuff as the stars” is plain modern astronomy: the elements in our bodies were forged in stars.
3. Chinese correlative cosmology — the five phases, each binding a season, color, direction, and organ, acting by “resonance” (ganying) — is documented in Joseph Needham, Science and Civilisation in China, vol. 2 (Cambridge, 1956).
