RĀHU MAHĀDAŚĀ — FAVOURABLE: In order to clarify the effects of the Daśā of Rāhu, I shall first mention the signs of exaltation and debilitation of Rāhu and Ketu. The sign of exaltation of Rāhu is Taurus. The sign of exaltation of Ketu is Scorpio. The Mūlatrikoṇas of Rāhu and Ketu are Gemini and Sagittarius respectively. The own signs of Rāhu and Ketu are Aquarius and Scorpio in that order. Some learneds have expressed the view that Virgo is the own sign of Rāhu and Pisces is the own sign of Ketu. Should Rāhu be in his sign of exaltation etc., there will be during the Daśā of Rāhu great happiness from acquisition of wealth, agricultural products etc., acquisition of conveyances with the help of friends and Government, construction of a new house, birth of sons (children), religious inclinations, recognition from Government of foreign countries and gain of wealth, clothes, etc. If Rāhu be associated or aspected by benefics, be in a benefic sign and be in the 1st, the 4th, the 7th, the 10th, the 11th or the 3rd house, there will be during his Daśā all kinds of comforts by the beneficence of the Government, acquisition of wealth through a foreign Government or sovereign and felicity at home.

राहु की वृष राशि व केतु की वृश्चिक राशि उच्च राशि होती है । मिथुन व धनु राशि क्रमशः मूलत्रिकोण राशियाँ हैं । कुम्भ व वृश्चिक क्रमशः राहु-केतु के स्वक्षेत्र हैं । कुछ विद्वानों ने कन्या व मीन को राहु का स्वक्षेत्र कहा है ।
