@Glennn,
I don't believe in karma that way. I believe that our actions/decisions results in what happens in our lives. For example, my travels have allowed me to meet people and become friends with them. They happened to be on the same tour/trip/site or lived in a town where I visited; karma.
I have also met many people through a2k. Moscow(Sergei gave me a private tour of Moscow when I visited there.), Lippstadt, London, Manchester, Mexico City, New York City, Houston, Austin, and San Francisco.
I have friends I met outside of a2k in the US, London (Lindsay Hamilton is a professional singer in London; I met her on a cruise), Malaysia, Singapore, Cuba, Mexico, and Moscow (Oleg; I met in Cuba).
My travel buddy is Canadian, but lives in Loreto, Mexico. We have traveled all over Europe, South America and Asia. We're going to Cuba next month.
