Two planets placed in each other's sign of essential dignity are in mutual reception, " en rapport". Mutual reception provides a harmonious link between planets not in aspect and strengthens the aspect if one exists.
When each of two planets is in the sign ruled by the other, a relationship is formed between the two that acts like a conjunction. For example, if Mercury (ruler of Gemini) is in Sagittarius, and Jupiter (ruler of Sagittarius) is in Gemini, the two planets are drawn together by virtue of their shared meanings, leading to beneficial effect.
When each of two Planets is in the Sign ruled by the other, a relationship is formed that acts much like a conjunction. (example; The sun [ruled by Leo] is in Cancer and the Moon [ruled by Cancer] is in Leo.)
see diagram) Two planets are said to be in mutual reception when they are in each other's signs of rulership. The example in the diagram is Mars in Taurus and Venus in Aries.Each planet has influence over the others' sign. Referring to one directs you to the other and then refers you back to the originating planet. Much like an endless loop. Because they are in each other signs they mutually support each other. A-Z
In astrology, mutual reception is a concept where two planets are placed in each other's signs of rulership. If the condition of each planet in mutual reception is strong, they will strengthen and provide assistance to one another. Some modern astrologers believe they will also take on some of each other's attributes.
