Mercury your Lagan lord and also 10th house lord is debilitated. It is very important to do remedies for Mercury.
You may recite mantra Om Braam Breem Braum Sah Budhaya Namaha 108 times daily.
Rahu in the Lagan in Virgo. You need to control from saying things that could put you in trouble. Control over your mind, intellect and speech is vital in your growth both personally and professionally. Rahu in lagan will make you highly tactful,as lagan is your personality and brain in kalpursh kundli. Sun in the 6th house is in a Shani rashi and Shani is in surya or Suns rashi making a wonderful exchange. Also Sun is the karka of profession and is in a favourable position from the 10th house. certainly career in politics can be explored, however like I said before use your rahu power discretely and you shall gain. Your Rahu mahadasha starts in 2022 , still very far. Basically rahu in the first house will make you complacent from the health point of view, so especial attention will be needed on the health front.
