In Breaking Dawn what does imprinting mean?? I am still very confused about it. someone please explain!!

imprinting is only for werewolves it is like love at first sight but a lot more intense. when a werewolf imprints they cannot stay away from that person, it is their soulmate and would do anything for them it is like magic they can't control it and no matter what the consequence is they will do anything to be with them. in the book it said that for the male werewolves it is the person destined to help produce the werewolf gene to the offsprings...it is the ONE AND ONLY PERSON FOR THEM... life is nothing without them...their is a really good explanation in eclipse... it is kinda hard to explain but i hope i helped...
