In Greek astrology, they give a major emphasis on the 10th house and its lord or the planet sitting in the 10th house to determine your career, but this is not true; why, you ask? Because greek it only relies on 1 chart, your basic birth chart, and, sometimes eastern astrologer, too, relies on the same chart. But, there is a bigger depth to this house.

(We’ll talk about it later) But a career is also seen from 2nd, 6th, and 7th house, too. 7th house is10th from the 10th house, which becomes your career house's career.
