Rahu, another shadow planet in Hindu astrology, is known as the ascending lunar node. It signifies *obsession, illusion, and materialism. Unlike Ketu, Rahu is associated with *worldly desires, ambition, and intense passion. Rahu can bring sudden changes, both positive and negative, and is often linked to unconventional paths. The sacred color for Rahu is dark blue or black, representing the mysterious and shadowy nature of this celestial body. Saturdays are considered auspicious for worshipping Rahu.
