Cazimi (also spelled Casimi, and sometimes called Zaminium) is a technical Arabic word meaning "heart of the Sun" or "in the heart of the Sun." It is an astrological/astronomical term meaning a planet that is in exact conjunction with or very near the precise center of the solar disc. A planet that forms a conjunction with the Sun within 17' (arc minutes) of partile (exactitude) is said to be Cazimi, literally engulfed and fortified by Sol and, as it also may be interpreted, "in the heart of the Sun."
