We have seen a huge proliferation in the market place of books, tapes, videos, and even phone line services targeting relationships using astrology as the vehicle. Most of these products only use the Sun sign as the tool for analysis with astrology. Some even go as far as throwing in the Moon sign as well. As with many English words, one word may have many different meanings, uses, and even pronunciations. This can be both a real problem in basic communication, and a strong tool in getting people to understand larger views.
Most people think and use the term as a quality of being as opposed to a state of being.
This kind of relating is a simple observation of the nature of the environment that the two exist in together. Using just the Sun and the Moon sign in looking at relationships is only looking at a fraction of the picture. These are essential archetypes in the Birth Chart, but what about the planet Mercury, which rules communication, or the planet Venus, which rules the essential needs sought through relating. There is also the Planet Mars, which rules the expression of your sexuality and the karmic energies. These additional points can help the astrologer develop a picture of the quality of the relating, as well as the necessity in what the individuals are relating for in the first place.
