In Taking Our Places: The Buddhist Path to Truly Growing Up, Norman Fischer quotes Rabbi Barukh's commentary on the 119th Psalm ("I am a sojourner on the earth; hide not thy commandments from me").
Barukh writes, "He whom life drives into exile and who comes to a land alien to him has nothing in common with the people there and not a soul he can talk to. But if a second stranger appears, even though he may come from quite a different place, the two can confide in each other, and live together henceforth, and cherish each other. And had they not both been strangers, they would never have known such close companionship."
Reminds me of making friends in Peace Corps. (Not that we're in exile.)
