These are the imaginary points in the sky. But even then, Rahu is considered most powerful and has been allotted the status of a planet by our Rishis and seers. Mostly, Rahu confers malefic effect. He is considered a dirty planet indicating laziness, filthiness, delays, and hurdles. He stays for 18 months in a zodiac sign.
In Hindu mythology, there is an interesting fiction that describes how Rahu and Ketu came into existence. Once both, the gods and the demons agreed to form an alliance to produce nectar that could give them immortality. Nectar was to be obtained by churning the ocean. In the process, nectar was churned out. When the nectar was being served to the gods, a demon, disguised as the God, and sat between the Sun and the Moon in an attempt to acquire the nectar. The demon was recognized by the Sun and the Moon who complained of the demon to Lord Vishnu. Lord Vishnu immediately severed his head from his chakra. But the demon had already consumed enough nectar to make him immortal. The head of the demon, known as Rahu, became immortal. And the remaining corpse of the demon was known as Ketu. Ever since Rahu and Ketu became the strong enemy of Sun and Moon. Sun and Moon eclipses occur due to Rahu and Ketu who swallow up Sun and Moon when they come near to them. In this way, Rahu and Ketu take their revenge from Sun and Moon.
In Vedic astrology, Rahu and Ketu are known as two invisible planets and they are strong enemies of the Sun and the Moon. Rahu and Ketu are actually the astronomical points in the sky respectively called the north and south lunar nodes. The places of the intersection where the Moon’s path meet the Sun’s path is known as North Lunar Node and South Lunar Node respectively. Thus, the relation of Rahu and Ketu with Sun and Moon has been described through the language of the symbol in Hindu mythology.
Rahu is a powerful and malefic planet. This is a favorable planet for the politicians. He gives them a great opportunity and power to rise in the politics through any means fair or unfair. He also rules over thieves, jail, magicians, snake, poison and isolated places etc. Rahu has also the power to confer sudden wealth.When Rahu is in the first house and it is only head it never be satisfied as it doesn’t have anybody with him whatever he eats goes infinite space then he eats and eats.In simple words, you can say the person never satisfied.you want more and more no matter what things you have already but the desire is on extreme .in any sign Rahu sits in it behave like that planet.this person does not feel themselves, confuse with their self-identity because Rahu is confusion.they want name fame money everything just for know themselves and when they got all then still say that God who I am???these people are very attention seekers of others, very social person.
But remember Ketu present in the 7th house who represent detachment, spirituality, letting go the material things, your expertise and due to expertise, these people are very good to create friends because they know the art of the deal.When they did not feel that they get enough attention of people they go to Ketu on their comfort zone they find someone who helps them to get attention.such a person may be short-tempered but he will be intelligent with a sharp mind and will achieve a higher position in his profession through his own efforts and ideas. The early part of life may be full of obstacles but the native will make full use of his efforts. He would like to enjoy the worldly pleasures. He has a lust for materialist life. If he fails to achieve in life, he is intelligent enough to enjoy other’s wealth. He will be wealthy and commanding. You can notice that when these people get married Suddenly they get success in their life due to Ketu as Ketu represent your past life karma/past life expertise .when person get married his/her 7th house become active.Ketu has person’s past life karma baggage also when its get activated person’s past life karma also get involve when they deal with marriage/legal partnerships.how good or bad it is it depends on person karma as which sign Ketu is or which nachhtra it’s in?maybe he/she get a very spiritual partner as Ketu represent spirituality
If Jupiter or Saturn is present with Rahu in friendly or in own sign then its good that Jupiter gives Wisdom to Rahu and Saturn makes him to Maintain discipline.If you think you have bad karma and you are suffering in Rahu/Ketu time period then if you become spiritual doing kriya yoga and gives help to getting fame for other people then you will be free from your bad karma.
