where fears and lies melt away

"thinking of you, wherever you are. we pray for our sorrows to end, and hope that our hearts will blend. now i will step forward to realize this wish, and who knows; starting a new journey may not be so hard, or maybe it has already begun. there are many worlds, but they share the same sky - one sky, one destiny."

i really despise the fact that the ending to kingdom hearts II has the ultimately rare ability to make me teary-eyed. don't worry, i didn't cry - now THAT would've made me look like a puss. i hate it when things happen like that; when you watch something so touching that it makes you happy and sad at the same time, and the feeling swells inside you to the point where it's so overwhelming that you can't help but cry about it - or in my case, get all teary-eyed. there are very few things in the world that can drive me to near-tears, and the ending to kingdom hearts II has just done that. mind you, this is probably the 583498234th time i've beaten the game, but this is the first time i've beaten it in a couple of years, so the impact is almost as strong as it was the first time i've beaten it.
anyway, skipping most of the nerd talk, the ending mostly spoke about the strength of the heart, and friendship and all that cheesy hullabaloo, and it got me thinking, like most things do. can the heart be seen as a weapon?
think of it like this: our emotions apparently stem from the heart. happiness, sorrow, fear, anger, all of those things come from the heart. when we hurt others by saying mean things or doing mean things, wouldn't we be channeling that spite through our hearts, since 'meanness' is an emotion?
i find it strange how there are people out there who try to research things that are obviously out of our control, like the workings of the heart and mind. how do you diagnose a mental illness? how do you know if that person is really insane or not? how do you nurse a broken heart? is it so simple to just pick up the shards and piece them back together? being the dominating species of this planet we try to take control over everything, including ourselves, but sometimes it's just not possible to be the boss of everything. the human heart is unpredictable, just as the human mind is. you can't choose who you fall in love with, or what your likes and dislikes are. you can't choose your mental capacity just as you can't choose who your enemies should be. i guess the idea of being in control is comforting to some people, which is why they go great lengths to do so. it still doesn't make any sense to me.
