Mark,
I'm assuming you mean when SOMEONE says they dies of a broken heart, not that I said that. I think that perhaps that is just an old saying that carries over and over from generation to generation. I doubt if you opened them up you would ever find a BROKEN heart. But I'm sure many of us know someone who gave up on life, so to speak, soon after a soulmate passed. I think this goes back to this broken heart issue. As to meditation and even the new findings that the heart has some rule over the mind I'm dubious. Maybe my mind is just stuck on stuck. Yet it seems to me to be a cause and effect issue. In your example of meditation for example; does the mental thought slow down the heart or does the heart slow the mental thought. I would say the former. But I just don't know. Thanks for spurring my thinking juices though!
