The ancient texts called the 3rd house by the name Goddess, citing that it was the place where the Moon rejoiced. This correlation was part of a system where each planet was the joy of a particular house and the name of the house was connected to the planet that rejoiced therein. Mercury rejoices in the 1st house of Life; the Moon rejoices in the 3rd house of Goddess, Venus rejoices in the 5th house of Good Fortune; Mars rejoices in the 6th house of Bad Fortune; the Sun rejoices in the 9th house of God; Jupiter rejoices in the 11th house of the Good Daimon Spirit, and Saturn rejoices in the 12th house of the Evil Daimon Spirit. 
When a planet occupies the house of its joy, it was exceeding happy and predisposed to bring forth the best of its own qualities. Furthermore, many of the meanings of the houses arise from the nature of the planet that rejoices in it. 
Enter into the realm of the Moon Goddess and discover how she bestows many of her own qualities into the meanings of the 3rd house, including sacred rites and observances, dreams, and divination. For the most part, these spiritual topics have fallen out of contemporary understanding of this sector of human experience that lists the main significations as communications, short journeys, and siblings.
