Mind and heart

The conflict of mind and heart has been enigmatic; it is these attributes of a human being that begets one more perspectives to think upon and makes choices more difficult.
I remember that dialogue from kabhi khushi kabhi gam “ jab bhi tumhe koi baat sataye, to aankhe band karo aur apne dil kee suno”. Does that mean listening to your mind makes you inhuman, or insensitive? Various movies and books have alluded to the fact that “heart” (of course that is a proverbial heart that thinks, otherwise heart is only a normal blood pump) is more concerned about your happiness and hence it is more human, and apparently happiness is the primary motive of all the actions of human.
But does it occur to you, that listening to your heart makes you more myopic and indulge in a happiness that is so fleeting and ephemeral. For e.g. a diabetic might be tempted to gorge on something sweet, such that he beckons his two his consultants, the mind and the heart. The mind would obviously rebuff the idea of eating sweet, but the heart would definitely say “yes sir”, your “happiness is more important”. Or a teenage couple might consider eloping disregarding the ramifications of their actions. True, the happiness is our only quest on this planet, but survival or sustenance is also important. That happiness at that instant might look the raison de’ etre, but happiness is something which ensues by various reasons and actions. What my point is, that though heart perceives happiness of the moment as important, it doesn’t see that very action as a source of future misery. Mind is more long sighted, and consults us deeming the long term sustenance and survival.
But then one might argue, that we are human and not machines. Machines need to perform and last long. Only existing is not the primary motive of one, but living is. It is important to be “in pursuit of happiness”, to feel the joy of being happy, the bliss of being human.

Lines i loved from the movie- stardust

Yvaine(the star) to Tristen

"you know when i said i knew little about love. that wasn't true; i know a lot about love i've seen it. seen centuries and centuries of it and its the only thing that made watching you world unbearable. all those wars, pain, lies, hate; may be i'd want to turn away and never look down.
But to see the way mankind loves. I mean you could search the farthest and farthest of the reaches of universe and never find anything more beautiful.
so..yes i know that love is unconditional but i also know it can also be unpredictable unexpected uncontrollable unbearable and strangely easy to mistake for
loathing.... but what i'm trying to say christen is i think i love you. my heart it feels like my chest can bearly contain it. like it doesn't belong to me anymore... it belongs to you.and if you wanted it i'd wish for nothing in exchange..no gifts no goods no demonstrations of devotion..nothing but knowing that you love me too. just your heart in exchange of mine."
