I had a similar experience of a conversation with an auto driver last week that uncannily answered some of the questions I'd been asking in my head (rather I'd been struggling with a diminishing of faith in life and felt reassured by that encounter). I love this account of your encounter with this wise man! When I hear of, or experience these events, I have this thought -- the divine hears our doubts and fears and sends a wonderful wise person as a channel to shore up our faith in the path of service with small, consistent acts
