Why do people fall in love?

No matter how intelligent, or how smart or how dynamic, we tend to think with our hearts. We might not admit at many times but we are emotional souls and thats what separates us from the animals. With all our experiences and incidents in life we are constantly judging people and creating a ideal picture of what should be there and what not. Once that picture is made or even the slightest idea is there we start looking for that ideal soul, who would complete us as a human being. We need a person who would understand us, who would believe us, trust us. And when we see a person who is having the slighest qualities of what we had thought of from time to time, and with the subtle qualities of the person itself, we love the idea of being around that person. Suddenly, the absence of the person leads to a void in our life. More we think of that person the more we are attracted to him. This is love. This is different from infatuation or attraction because infatuation and attraction are temporary phenomena and many times is dependant upon beauty. Whereas, love transcends physical beauty. It is what lies beneath ! Love helps us realise our incompleteness and gratifies our soul. Thats why we fall in love, be it with our wives, husbands, children, parents, friends, anyone.
