Mangalik Dosha or Bhouma Dosha

Most of the astrologers know that when Mars is placed in the 1st, 4th, 7th, 8th and 12th house from lagna , then this dosha created. Here is small mistake. The 2nd house also must be concerned in this and counting must be both from lagna and rashi(Ascendant and Moon sign). So when Mars is placed in the 1st, 2nd, 4th, 7th, 8th and 12th house from ascendant or Moon sign then Manglik dosha or Bhouma dosha is created.
