Learn about Arabic Parts (Lots) — calculated points using the formula ASC + Planet A - Planet B. Understand the Part of Fortune, Part of Spirit, and other significant lots.
What Are Arabic Parts?
Arabic Parts (also called Lots) are calculated sensitive points derived from three chart factors, usually two planets and the Ascendant. The formula is typically: Lot = ASC + Planet A - Planet B. Despite the name, they originated in Hellenistic astrology and were later developed by Arabic-era astrologers.
