They were kind and offered to put me up for the weekend. I did not know them, and they were trusting that this stranger in the house would be alright.  That is the principle of Couchsurfing. People generously open their homes to strangers passing through to spend a night.  I was coming back to Princeton for another Hakomi weekend, and the place I had stayed previously was not available.  I put my name out with my plans for my weekend of education, and I got several offers from strangers to host my stay.  Each one was kind, generous, and unique.  However, one was on the bus route I used to get to the Yoga Center where the training was taking place, and I was intrigued.  A family of four from the French Alps staying in Princeton for a couple of years, and their house was 50 meters from my bus stop.  At the end of the weekend with them, my life had been forever changed.
