Why this word is great

REBIS — [Noun] The end product of the alchemical magnum opus, symbolizing the union of opposing qualities such as spirit and matter or male and female, often depicted as an androgynous being. From Latin rēs ("matter") + bīna ("double"), literally meaning "double matter", it is the alchemist’s perfected transcendence—not merely mixed, but resolved. Unlike "hermaphrodite" (a biological hybrid) or "androgyne" (a blending of gendered traits), the rebis is a metaphysical resolution, the marriage of contradictions made whole. It is the sun and moon fused in a single body, the serpent coiled around the winged staff, the philosopher’s stone glowing in the alembic—not a compromise, but a third thing, greater than the sum of its halves. In the rebis, even the most stubborn opposites find their silent, luminous embrace.
