Well love, just like any other human emotion, is a burst of chemicals into the bloodstream. I don't remember the chemical's names, but there is a separate one for love, fun, sorrow, scare and other emotions.
Basically, when you see someone you are "in love with", or you're thinking about that person- your brain automatically does the job, and you get this experience of "love".
Very simple.
Now it gets very very difficult when you are trying to control these processes. Not that easy to control your brain, you know. Imagine not being afraid if you see something really scary.
But how beautiful would life be if you can keep all your sences under control and enjoy them only when you really want to!
