Attraction is something that even the smallest of an animal would like to have, everything in this world attracts. The flowers attract the bees; the babies either of human or of animal or bird are attracted towards their mother.
On top of everything even our world has the magnetic force of attraction. When the Lord God created this world and everything that lives upon it, and when he created the heaven he also created attraction, this attraction is something that holds us to the ground and holds us near to each other and close to each other. Though attraction has a vividly wide meaning but we will narrow the same to attraction between two different sexes.
A time comes in our life when we are attracted knowingly or unknowingly to our opposite sex which in other term is named as lust, crush or love. This is so pin pointed kind of attraction because this attraction happens suddenly, just imagine a person whom you have never met, never spoke to or heard about and you see the person suddenly and there is an urge inside you to meet the person, speak to the person or be with that person, this is attraction.
