Conjunctions
When two planets become conjunct their energies combine and become enhanced. Depending on the planets and their elemental nature and placements a new “thing” happens with the planets.
It is just as important to know the qualities of the planets that are being combined so one may correctly judge the energy and realize the potential of whats happening.
Note what house the conjunction occupies and how many planets are conjunct. Also remember that in the case of a conjunction the planets involved tend to have the same aspects and therefore must be calculated with each other when delineating a chart.
