In this video, Vinayak Bhatt Ji talks about how being a good astrologer means doing more than just looking at a person's Lagna or Rashi to give advice in Vedic Astrology. He explains that you need to know the right way to pick remedies concerning freewill and fixed karma.
Vinayak Bhatt says that there are many things besides Lagna or Rashi that affect which remedies you should use. You have to think about where the planets are, how strong they are, whether they are causing problems, and other details from a person's birth chart.
