My friend who is not a professional astrologer told me that I have very bad Kalasarpa Dosha and I should perform some remedies....I have no problem in performing the remedies but when I checked my horoscope on few websites it showed me that I dont have Kalasarpa Dosha.....What worries me is that according to my friend I have a very negative Kalasarpa Dosha....can anyone please check my horoscope and clarify....
