If I am full of myself, there is no room in me for what you bring. I keep myself intact when I convert you; I keep myself intact when I politely tolerate you; in a mutual interaction, I lose something of myself to create an opening for your perspective, your experience to enter my world…
'Be not forgetful to entertain strangers: for thereby some have entertained angels unawares' (Hebrews 13:2). This ancient advice to “entertain strangers,” to be open to others, to invite them in and offer them food and listen to their stories, point to the reward that comes from this “entertaining,” this response of mutuality: in that other, we may just find an angel.
Now I admit that I have never seen any sort of mystical angel, a divine glowing being with halo and wings, and I suspect I never will. But I have met a fair number of angels in human guise, if an angel is also someone who offers me something I never expected to receive, tells me something I never expected to hear, shows me something I never expected to see, helps me understand something I never expected to grasp, or otherwise breaks into my usual mindset. When another manages this feat, moving past my defenses and my absolutely true opinions to remind me that I really, finally, do not know everything, then I have been visited by an angel."
