The first part, does Compassion for oneself mean never falling in love? If we think of the ultimate, in Buddhist ideals "the end of the road", to end all desires, means we're going to end all suffering. Fine, if you have Compassion for yourself on that level, by all means do not fall in love. That is the end of the road. However most people aren't ready for that.
Some people, when they fall in love, can't stop it happening because of past Kamma. Buddhism would say it's got to happen, there's too much attraction between these two people due to past connections. Some people refer to that when they first meet as "Love at first sight". Rosemary and I had "Love at first sight" and it was too strong to deny, but granted we weren't into Buddhism at that time. We were just young teenagers.
Now looking at it in another way, because Rosemary and I fell in love, because we married, that's why I'm sitting here. I wasn't interested in meditation, she brought home the book. I didn't want it, "Religion - that's for people who suffer, not me, I'm not suffering." She got us into meditation. Not only that - she found the first Buddhist temple, not me, she was looking in the newspaper, not me. So little things like that which Rosemary did helped me and I got here. And in that way, our love has helped thousands of people.
But falling in love has other meanings, too. Ananda, the attendant monk of the Buddha, could not become fully enlightened while the Buddha was alive because he was too attached the Buddha. Ananda wanted to do everything possible, to serve the Buddha in every way, to wash his bowl, clean his clothes, whatever he could do. And because he was so attached to the Buddha in this way - he could not become fully enlightened while the Buddha was alive. However, this strong attachment produced a lot of the scriptures that we have because a large portion of the Suttas are recorded to have been what Ananda remembered the Buddha said.
Whenever you read the scriptures and they begin with the words, "Thus have I heard..." Every one of those scriptures was recorded by Ananda. He remembered them because he stayed around the Buddha so closely and because he was so much "in love" with the Buddha, he memorized all these things, wanted to keep it all. And because of that he passed them on and today we have so many scriptures. So that type of falling in love with your teachers, supporting them, helping them, could end up being of benefit for lots of people.
