The conjunction Rahu + Mars
The combination Rahu + Mars is also called Vijaya yoga, which means a striving for victory by any means and a lack of scruple about them. It strengthens the energy of Mars — the person needs to be constantly in action. The other side of it: aggression, cruelty, insensitivity.
When the link between Rahu and Mars comes about through an aspect, it shows itself more gently. This combination strengthens the non-living indications of the house but spoils the living ones. In the 4th house, for instance, it may give real estate and strong intuition, but will create trouble with the mother and destroy inner peace, and may make the native cunning and cruel.
For Albert Einstein, Mars + Rahu in the 8th in Capricorn gave unique research abilities: he made a discovery of world importance.
The conjunction Rahu + Mars in the horoscope of John Lennon
John Lennon was the founder of The Beatles. A Vargottama Lagna — that is, a double Virgo in D1 and in D9. The Lagnesha Mercury stands in the 2nd house in the Hora Lagna and the Ghatika Lagna, which gives wealth and influence.
The atma-karaka Sun stands in the 1st house with Rahu and Mars (the lord of the 8th and the 3rd houses). Conflict with the authorities: he returned his order to the Queen of England, was in conflict with the government of the United States, and was a harsh social critic.
He carried out his task by Rahu through Mercury in the 2nd house: songs, public rallies, the struggle to end the war in Vietnam. The Lagna has shubha-kartari from Mercury and Venus: fortunate, talented, rich. His popularity soared in the period of Rahu from 1960 to 1977. Rahu stands in Hasta (the Moon), which is Vargottama and the lord of the 11th house — success and profit.
Death came in the period Jupiter-Saturn (both planets stand in the 8th house of death). Jupiter is the badhakesha. Saturn is in fall. In D9 the Lagnesha Mercury is in fall and in conjunction with Mars, the lord of the 8th house. He was shot by an envious fan — that is how Mars showed itself in the role of the gnati-karaka.
(from the materials of Vasily Tushkin’s «Surya-Siddhanta» school)
If a conjunction of Rahu with Mars is present in the chart in the 2nd, the 10th or the 11th house, the person receives income from secret and doubtful sources. (Shri G. S. Agarwal)
Rahu + Mars
A weak Mars and a strong Rahu give trouble in one's affairs, confusion in simple rational conclusions and a muddle in carrying out tasks. I strongly advise against taking such people into production posts: there will be more trouble from them than use. Besides, it is hard to prove to them that they are imperfect. Common sense is also disturbed.
If Mars is stronger than Rahu, the highest practical skills and thinking show themselves. Such people can create paradise in a hut, make a tasty dish out of simple ingredients, and organise a business, a production line, their own work and the work of those in their charge to perfection. This combination is honed for rationalism, optimisation and production.
