Rahu is the planet of chaos and unpredictability in Vedic astrology. This shadow planet is known to bring sudden changes or twists in one's life, both positive and negative. When placed in Shravana nakshatra, the results could vary based on the pada it falls under. Shravana nakshatra is ruled by Lord Vishnu and brings an aura of learning and knowledge, making it a favorable placement for Rahu.
