The Srikalahasti Temple, located in Andhra Pradesh, is renowned for its powerful Rahu Ketu pooja, a special ritual believed to mitigate the malefic effects of Rahu and Ketu doshas. Rahu and Ketu are shadow planets or lunar nodes in Vedic astrology, known for their influence on a person's life. They are believed to cause challenges, obstacles, and karmic issues, particularly if they are negatively placed in a horoscope. Performing the pooja is believed to bring balance, peace, and positive energy, mitigating the adverse effects of these shadow planets.
