For as many names as there are in this world, there are as many reasons for choosing a name. For example, some parents use astrological signs to name their baby. "A name that harmonizes with a person's birth sign is a powerful choice because it enhances the characteristics associated with that sign," says Phyllis Vega, a professional astrologer, Tarot reader, and numerologist in Miami, FL. Her book, "Your Magickal Name: Using Astrology, Numerology, Myth and Meaning to Choose the Perfect One," examines the elements a name is composed of, from number value, astrological correspondences and mythological associations, to historical significance, spiritual implications, origin, and meaning.
