Sadly fabfan, you have posted twice, which means you are disqualified from this question. (That isn't including the double post).
From what I heard it was an Indian person who appeared out of nowhere on a bicycle, cycled up to George, gave him the book, then cycled off again, but you lot think it was Swami Vishnu Devananda. I won't finish this question yet, so the people who said it was the swami can show me quotes. Otherwise it's Sally who gets the point.
