Rahu in the 2nd house in Vedic Astrology makes the native fight or argue with his or her family and relative, he or she has a different view on the family, and usually these folks either move out of the house at an early age or they move to a foreign land, as Rahu in 2nd, 4th, 9th, and 12th house take a person to foreign lands.
The 2nd House in Astrology represents family, fixed assets, speech, family business, possessions of things, throat, this also includes married life (some only count 7th house as a marriage house, but 2nd and 4th is also important as they rule the home life in eastern astrology) This house is also death inflicting house (Marka House). Marka simply means houses that mentally & physically kill you, as 2nd represents the family, it will make you work, think, argue, fight and disagree with people in your family if it is ill in your chart. The negative aspect of such house can drain any person to their death.
The second house in Vedic Astrology represents the family we are born into, which we get immediately after birth. Along with the family, we also get the social status of that family that determines to a certain extent our financial future. Therefore wealth is signified too.
Physically, the face is part of the body next to the skull. The face, eyes, nose, and mouth are all signified here, and so are eating and speaking, which are done with the mouth. The correspondence with Taurus (fixed, Earthy, and ruled by Shukra. (Venus)) adds to the signification of wealth and luxuries. You have the Moon in this house. Therefore it is an important house.
Rahu is the north node of the Moon and is a head without a body that keeps devouring things without ever being satisfied. It has a desire for material things and worldly accomplishments. It wants to achieve the highest success possible in whatever house and sign he represents. Rahu represents the goals that have been set by the universe for us to achieve whether we like it or not. Rahu is mainly known as the eclipse, and it eclipses the Moon and the Sun whenever it's in conjunction with them. This means temporary darkness upon the native's life when the Sun and Rahu are in conjunction in a birth horoscope.
Rahu also brings fear and stressful situations into our lives. This is due to Rahu's adventurous nature that loves surprises. With Rahu, sudden events take place; events that may not be a real part of our lives but rather an illusion that becomes reality.
Rahu in Vedic Astrology is a very unsteady and erratic force ruled by obsessive passions and unconcerned with ethical notions of right and wrong. Because of this, Rahu can bring great material progress, though any success gained under its influence is likely to be short-lived. Rahu is tricky and sneaky, and creates illusions of all kinds.- It especially manifests in one's compulsions or uncontrollable passions.
Note : The degree of auspiciousnes and inauspiciousness will depend upon the complete analysis of the horoscope (Birth-Chart).
