What is it about opening our door to strangers that makes this a central spiritual quality? The Torah tells us to love our neighbor only once (Leviticus 19:18) but urges us to love the stranger more than thirty times! Why? Hospitality requires that we step beyond the dualistic thinking of self and other, us and them. You open your door only after you have opened your heart. Hospitality is then an accurate reflection of the quality of your spirituality.
