The North Node of chandra (Moon) is called Rahu in Hindu astrology. Rahu is not a material embodiment and is referred to as chaya graha (Shadow planet). Rahu is the northern point where the path of earth around sun cuts the path of chandra. When moon, sun and earth come in the same plane near to rahu the eclipses are caused. Rahu is a malefic and afflicts the planet he is associated with. He is the significator of any sudden event be in an accident or a lottery gain. He indicates secrecy, dissatisfaction, hidden enemies, greed, proficiency in foreign and artificial languages like computer languages. He represents foreign or alien culture, obsessive personality, mass tragedies and mysterious diseases. He causes abortions, rifts in married life as well as domestic problems. In certain houses in the chart rahu is better for example, in the 6th house. Regular propitiation measures to rahu removes above problems. The possibility of accidents, snake bites, allergy etc., are reduced.
