I like this information very much that you are an astrologer and you are from Banaras. Your M.A. Siddhant has studied Astrology and now you are thinking of doing PhD, that is very good. Astrology is a very important thing which helps in our future. May you be successful in your endeavors, and may you further develop your knowledge. Studying gender and its importance in astrology can also be a valuable topic. We should gain knowledge by studying how gender studies can impact astrology. By doing a PhD, you can spread your ideas and knowledge to even more people. Best of luck for your future endeavors!
