Find your North Node: https://www.trulydivine.com/astrology/find-your-north-node
What’s your life purpose? In your birth chart, the lunar nodes—known as the north node and south node—hold the keys to your destiny and ultimate life lessons.
Your life purpose is encoded in the north node and south node of the moon. The lunar nodes are directly opposite each other in the chart. They aren’t planets, but rather mathematical points on the chart that fall in two opposite zodiac signs. For example, if your north node is in Capricorn, your south node will be in its opposite sign of Cancer, and so on.
