In Vedic astrology, the placement and condition of planets in different houses of the natal chart play a significant role in determining an individual's life events and personality. Rahu, also known as the north node of the moon, is a shadow planet that has a powerful influence on one's life. When Rahu is placed in the 9th house for Aquarius lagna and aspecting houses 11,3,6, it can bring both positive and negative effects to the native's life.
