The Brain on Love, a fascinating account from the NY Times Opinionater blog about how love physically changes us. My favorite paragraph:
When two people become a couple, the brain extends its idea of self to include the other; instead of the slender pronoun "I," a plural self emerges who can borrow some of the other's assets and strengths. The brain knows who we are. The immune system knows who we're not, and it stores pieces of invaders as memory aids. Through lovemaking, or when we pass along a flu or a cold sore, we trade bits of identity with loved ones, and in time we become a sort of chimera. We don't just get under a mate's skin, we absorb him or her.
Being privately spiritual but not religious just doesn't interest me. There is nothing challenging about having deep thoughts all by oneself. What is interesting is doing this work in community, where other people might call you on stuff, or heaven forbid, disagree with you. Where life with God gets rich and provocative is when you dig deeply into a tradition that you did not invent all for yourself.
