Astrological concepts are based on the belief that the positions and movements of celestial bodies, such as planets and stars, can influence human behavior and events on Earth. Central to astrology are the zodiac signs, which are divided into twelve segments, each associated with specific personality traits and characteristics. These signs are determined by the position of the sun at the time of a person's birth. Another key element is the natal chart, a map of the sky at the moment of birth, which provides insights into an individual's strengths, challenges, and life path. Astrologers interpret these charts to offer guidance and predictions, often using aspects like houses and transits to analyze how celestial movements affect personal experiences.
