The constellations serve as the lens that energizes and personalizes the planet. It has been scientifically proven that stars produce a gas. Groups of stars in a particular configuration (constellation) produce a specific gas and when a planet passes in front of one of these constellations it is fueled into action. Planets represent particular psychological drives, urges and motivations. The drive of a planet is expressed through the “sign” in which the planet is moving.
For example, Mars asserts, Venus harmonizes, Jupiter expands, Saturn restricts, etc. If Mars is in the constellation of Taurus it will assert itself in a slow and steady manner. It’s placement by house determines the exact area of life in which this slow steady action can be most obviously observed. Very simply put, the planets show what is happening, the signs show how it is happening, and the houses show where it is happening!!
