It is truly a blessing when some one comes into your life and your souls are inextricably entwined. No matter how hard you try, to want, to have it not be so, you know that you have been with this soul for all eternity and will be in relationship for all eternity. Whether that be as friend, mentor, partner or lover, it will be. You know this on sight despite the blinders you wear, and regardless of how you want to define this connection the Universe will put it in the proper perspective. This is Soul recognition when you see it, it is beyond words.
I am blessed to have had this experience on a very few occasions
