Soul mates may come in many types, shapes and sizes.  Your soul connections may include people that you owe something to in a Karmic sense.  These connections usually only last until some sort of Karmic debt is resolved.  This process may be very quick or take a little bit longer - depending on what needs to be resolved.  You could find your Twin Flame soul mate.  This intense connection reflects your other half and may be very challenging:  Have you ever won an argument with yourself?  Other connections include simply romantic, familial, friends, etc.
