The rule for us all is perfectly simple. Do not waste time bothering whether you 'love' your neighbor; act as if you did. As soon as we do this we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him [or her].
It's true, you know. I wrote about my airport experience several days ago--the part where I go in with a Love Bomb and people are nicer. I've been doing that more and more. I don't know about anyone else, but I feel better.
Good enough. And if it changes them as well as me...so much the better.
