Ketu (Dragon's Tail) Puja is dedicated to planet Ketu. Grah Shanti Ketu Pooja (Worship of Dragon's Tail) is recommended for those, having malefic Ketu or wrongly placed Ketu as per the horoscope. In Vedic astrology, the South Node of the moon is called Ketu. Ketu is known as a shadow planet, because of the Node's association with the phenomena of eclipses. Lord Ketu is supposed to have the head of a snake and the body of an asura (demon). The temperament or nature of Ketu is fiery. Ketu is the planet of spirituality. If Dragon's Tail is malefic in one horoscope chart then Ketu Puja is recommended to remove the malefic effects. People afflicted by malefic Ketu are stricken with fears of robbery, bad habits, putra dosham, loss of property, and loss of face. Reciting the following mantra after sunset, facing north - west direction, will really help to reduce the bad influence of Ketu.
