The South Node in astrology represents past life experiences, ingrained habits, and comfort zones. Its sign and house position show skills you've mastered and patterns you're meant to evolve beyond in this lifetime. For example, a 10th house South Node suggests past focus on status, now calling for greater emotional fulfillment. Understanding your South Node reveals karmic lessons and where you're being challenged to grow. It's a powerful tool for soul evolution and breaking free from limiting patterns.
