You recognize them

My Uncle Ben wrote me a letter twenty years ago in which he said, "Sometimes you run into someone, regardless of age or sex, whom you know absolutely to be an independently operating part of the Whole that goes on all the time inside yourself, and the eye-motes go click and you hear the tribal tones of voice resonate, and there it is--you recognize them."
