According to some sources, it came to be a symbol of love in the sense that the heart is the most closely related to our true being. In short, it is closely related to our deepest core. Read more at http://en.wikipedia.org/wiki/Heart_(symbol).
Maybe cause when you're in love, adrenaline pumps through your body when you are excited to see them. you feel the adrenaline increase your heartbeat, so maybe that's why the symbol for love is a heart,
In all actuality there is a level to this question that most don't realize. Have you ever wondered why the heart symbol bears no resemblance to the human heart. The two popular beliefs of its origins are: 1. The seed of the silphium plant (an ancient herbal contraceptive). 2. One of a few parts of the female anatomy. I.E.: Caboose... :). "Fat bottomed girls, You make the rockin' world go round." lol
According to me Well... the heart beats and when you say you love someone you're more likely to say my heart beats for you which means your are my life and that was used in novels since long time ago! i think it's a great question, made me wonder and didn't get to the right answer =S
the true reason................earlier,many centuries ago,people believed the presence of ' The Soul ' and that the soul was the reason for ones actions and behaviour.....so,phrases like 'with all my heart'[soul] came into existence.....................Later, it was found that the brain was the reason for our actions ...........but,the sentiment still continued with the people............even today people believe in the soul
Since the heart looks nothing like the heart shape we use to represent it, it seems odd that this symbol represents our heart or soul. I read once that the heart shape came from the pattern that a wet behind makes when seated on say a bench. Since love-making is done in the nude, it would seem to make sense that this symbol relates more to love making than to love, but it's a short hop from one to the other.
well its because the heart is supposed to be where your soul lies and when you are in love with someone you heart beats faster when you see then or think of them therefore you feel your heart belongs to them
