Astrology is the study of the influence of celestial objects, such as the Sun, Moon, and planets, on human lives. It examines the positions of these cosmic entities at the time of a person's birth to understand their personality, relationships, finances, education, and other life aspects. Astrology provides valuable insights into an individual's strengths, weaknesses, and potential life path through horoscope readings, birth chart analysis, and astrological sign interpretations.
