We do not always agree to come here at the same time. They could be your Mother, your best friend or your child. Your soul mate in this lifetime could be your cousin or your sibling. The point is that a soul mate is any person that you feel a strong love and bond with. When you feel as if you have known someone forever, when you are totally comfortable together and are in harmony with one another, this can be your soul mate.
Soul mates have nothing to do with lust or sex.
It simply means that you are strongly physically attracted to them. You must remember that you are also bound to meet people in this lifetime that you have a Karmic bond with that is based in negativity. We all have Karma to transmute that has to do with people we have wronged in a past life or who have wronged us. Sometimes, this bond is mistaken for love. If you are in a relationship with someone, friend or lover, where there is a lot of pain or disagreement, it could be this type of connection.
