Good and bad planets for Sagittarius ascendants /Dhanu lagna
Sagittarius is ruled by Jupiter. For any amendments 3,6 and 11th lords are malefic. Will see in detail....
Good planets :
Mars: as the lord of 5th and 12th houses gives good results. As Mars is friendly to Jupiter, and also Mars had its moolatrikona in 5th House series, so Mars gives mostly the 5th House results.
Sun: Sun the lord of most spacious house 9th, gives benefic results. Even Jupiter and sun are friendly to each other.
Jupiter: as the lord of Lagna, also having moolatrikona in 1st house Jupiter gives good results. As a natural benefic ruling 4th, a Kendra house, some texts say that " kendradipatya" dosha applicable to Jupiter. But here 1st house is also an angle, any planet rules a Kendra and angle houses become a most auspicious planet. Mostly Jupiter can be treated as a neutral planet.
Bad or negative planets : Venus: as the ruler of 6th
and 11th houses, Venus gives bad results. Even Jupiter and Venus are natural enemies.
