Soulmate and Supersoul

Came across a superb comment by another wise believer, Robin -

We are all witnesses to God’s love for dualism. Everything he made is symmetric. The temple (body) itself is symmetric where otherwise we observe no other perfect geometrical properties (e.g in nature we do not observe perfect squares or triangles).
I believe that our souls are a part of the God, his soul, the Supersoul. Then assuming that He separated a part of the His soul (Soul is infinite and after parting remains complete) and we were created. But then, conditioning such a powerful force by body made of dust was a problem OR He thought such power of the soul if separated might turn dark so he divided the part into two. Divided, the soul had lost most of its potency and united it would regain it. And maybe this unity of the two souls is the ultimate objective of our long journey though the material worlds.
Of course their is attraction towards other in this journey, sometimes a bond so strong that’s indistinguishable from true love; but our souls are, in fact the same, of a same source. But what is like us is different and stands no match for what is US. The Other Half is not somebody with habits/hobbies similar to ours, but they complement us, they complete each other. So a person who likes music maybe has a soulmate who can sing or play the way he likes and not the one who likes the same music.
Souls can have any gender, gender is unimportant. Gender is just a doorway for other souls to come to the Earth. Sex is for reproduction, but sexual intercourse between two soulmates makes them ‘of one flesh’, the two souls are united the deepest way humanely possible and this is purity and sanctity.

Also, a common observation: Most soulmates who’ve finally met die young, for they have no other reason left to be continuing he journey. They unite after death (often die just after the other) and become one soul and finally unite with the Supersoul. The true Trinity is then complete.
