• Chara Rashi (Movable sign) 1,4,7,10
• Dwiswabhawa ( dual sign) 3,6,9,1
• Sthura ( Fixed Sign) 2,5,8,11

If the lagna falls in Chara Rashi in sign 1,4,7,10 ie. Aries, Cancer, Libra, Capricorn  ( MA, MO, VE, SA respectively) and Lagna lies in 1st drekkan ie. 1st 10 degrees, the results of the Lagna Dasha are auspicious, in 2nd 10 degrees, results are medicore, and in 3rd 10 degrees the results are adverse or ordinary.

In Dual signs in Dwiswabhawa ( 3,6,9,12 ie. Gemini, Virgo, Sagittarius and Pisces) first 10 degrees adverse results, 2nd 10 degrees medicore results and 3rd 10 degrees auspicious results

In fixed signs (ex. 2,5,8,11 or Taurus, Leo, Scorpio, Aquarius) 1st 10  Drekkan proves adverse, second auspicious, and third medicore.

This is a very important clue about results to be expected from Dasha of Lagna. Thus results does not depend on the nature of the Rashi but also on the Drekkan which such Lagna falls into. (each Rashi/sign has three Drekkans which measures of 10 degree arc)
