Re: Followers of Hindu philosophy
To ssingh's contribution, I'll add a small one. All we've been and Einstein has been saying is that you dont have to "convert" to Hinduism to follow its tenets. What the Bhagawad Gita and many Hindu scriptures say is universal.
As for actual conversion figures from foreigners, then yes there have been thousands of foreign converts to Hinduism who are in the ISKON movement, or followers of Sri Sri Ravishankar or Satya Sai Baba (a suspect actually).
Even Appless' Steve Jobs used to fo to the Hare Krishna temple in the US after the left University and made history with Apple computers.He often mentions it in his speeches.
I believe that sadiyah sahab is asking for "out-of-the-blue" conversion figures, (like that Afghan convert to Christianity). In that case,I'm afraid I dont have any figures. It could be any number.
