Boomerang

"

Analogy VENUS / SATURN

The Boomerang has the same base as the Yod, but with the addition of another planet opposite the focal point or reaction point. This planet represents self-image, forcing the person to consider what is causing internal obstacles in a lucid way. Confrontation is inevitable. The planets in opposition enable an in-depth reflection and transits of these points activate situations which can help to solve the problem of the obstacle in question."
