The Better Houses for Saturn and Rahu

The houses where Saturn or Rahu is generally easier to live with are the 3rd, 6th, and 11th. Those are upachayas, houses that can grow with effort. The 3rd takes courage and skill. The 6th takes competition and the ability to answer an opponent. The 11th takes gains. A malefic in an upachaya is expected to build. The same planet in the 7th is a marriage complaint, and in the 8th or 12th it is a dusthana weight.

The reason is the house type, not a moral ranking of the grahas. Saturn's 19-year mahadasha and Rahu's 18-year mahadasha then spend a house that can use pressure.

Saturn is exalted in Libra and debilitated in Aries, and it has directional strength in the 7th. So Saturn's best sign is Libra, which may or may not be an upachaya, depending on the lagna. For a Cancer lagna, Libra is the 4th, and an exalted Saturn there is in a kendra, not in the 3rd, 6th, or 11th. Directional strength in the 7th pulls Saturn toward the marriage house that matchers dislike. The best house and the best sign can argue.

For Taurus and Libra lagnas Saturn is yogakaraka, so its best role is lordship, not a universal house. Rahu has no agreed exaltation in the texts that actually agree, and no yogakaraka lordship, because Rahu rules no sign.

Rahu in the 11th is often the cleanest Rahu, with Ketu in the 5th as the price. Saturn in the 11th is a slow gain. Saturn in Libra in the 7th is exalted and directionally strong and still a 7th-house Saturn. Calling that the best house because of digbala and the worst house because of marriage is an honest contradiction. State the question. For labor and income, prefer the upachayas. For Saturn's own dignity, prefer Libra. For marriage peace, do not volunteer the 7th.

Rahu does not borrow Saturn's Libra prize. Keep their addresses separate after the shared upachaya rule.
