Hey,
Rather like praying? "May all beings be happy" etc. [...] to me it felt a little contrived
I would like to explore these teachings in more depth, although do not feel confident that I can bring sincerity to them at present.
While staving off this suffering through laughter may lead to temporary happiness, I don't see how it could reveal the truth of a given situation. Forgive me if this sounds impertinent.
Yeah, I've had these attitudes & thoughts myself, so you're not alone here. I also agree that best love/compassion/etc. is based on clear understanding and empathy. Let me just briefly add a few thoughts to the other posts:
- I think you can improve your baseline level of goodwill & happiness with practice.
- "What a person considers and reflects upon for a long time, to that his mind will bend and incline." This in particular applies to thoughts of good will and compassion. I'm starting to see this happen with myself.
- Good will & happiness are very much related to non-clinging/non-grasping, which is in turn the basis for samadhi, mindfulness, peace/ease/freedom, non-delusion, and much insight (in my experience).
Your other comment regarding samadhi makes me wonder ... have you found it helpful yourself?
My samadhi practice right now is basically just practicing non-craving during the day and on the cushion. I find I actually get a surprising number of insights from it -- it requires a lot of mindfulness of the mind and feelings, and goes very deep. Honestly I'm not very good at it, but to the extent I can relinquish grasping, I feel much more at ease, find the present moment much more easily, and have good mindfulness. I can see why when the Buddha remembered jhana he felt it was the path he was looking for. But for me this is a subtle practice, and I'd probably be taking a big risk if I just did this and didn't practice some straight vipassana too. So I try to hedge my bets.

It seems important to me though.
By the way, check out the Karaniya Metta Sutta:

And if you poke around in the other suttas, you'll find that the Buddha was big on non-craving, renounciation, etc. I'm trying to follow 6-step training and the eightfold path (http://www.accesstoinsight.org/ptf/dhamma/index.html), and it's a major part. The whole thing seems very comprehensive to me, I'm quite impressed. I just hope I don't throw myself (and anyone else) off track if what I should be doing is just noting sensations ...
