Historical root
The popular phrase is associated with interpretations of the Emerald Tablet, a short alchemical text transmitted through Arabic and Latin traditions. Modern wording varies by translation and paraphrase.
Macrocosm and microcosm
Esoteric writers often use the idea to connect the human being with the cosmos: patterns in one domain are treated as analogues of patterns in another. That can function philosophically or symbolically without implying a testable one-to-one scientific law.
Modern use
Today the phrase appears across Hermeticism, astrology, manifestation content and popular spirituality. Its flexibility is why it travels well—and why context is important whenever someone presents one interpretation as the only original meaning.
