Significations have been assigned to all astrological factors i.e Signs, Planets and Houses.
Most of the astrological books will start with these signfications and then there may be chapters for combination of two factors like Sun in first house, sun in second house and so on . Similarly you may find chapters like Sun in aries, sun in taurus and so on. In costellation astrology , you may find sun in Aswini , sun in Bharani, and so on.
