Twin flames have a Divine spiritual connection.
They are incarnations of each other because they share identical souls. This is where it starts.
Aside from the personal testimonies of each twin flame, there is no scientific proof, beyond the side-by-side presentation of the facts of two people who lived parallel lives. What happens to one twin flame, happens somehow to the other twin as well.
The details for each one may be different, but if one twin cries, the other may cry too, sometimes, for no reason. If one twin schedules a vacation to a certain country, the other twin may do it too. But, generally, you have your own free will, and that’s why you go through certain life paths that bring you closer to your twin or far away. And at a divine time, the twins supposedly meet by coincidence, as their souls work on this, for so long, in the background.
Why do two twin flames meet, even, for once in this life?
Maybe science has no words to say about this topic, but souls and of course your guides know the answers well. Briefly, you can say it’s not scientific evidence. However, when you line up all the events side by side, you may remark that there are parallel events that happened to both of you. A lot of things look different on the outside, but they are so similar. Sometimes, you just need to admit that you just have to listen to your intuition as you move forward on the journey of the twin flame.
Let’s say in the end, what should science do?
Scientists have to study the reaction of the eyes when the person meets their twin flames. And, as well all know, eyes react to lights. The pupil gets bigger or smaller in response to changes in light. Even if it is not for the rest of the world, for you, your twin is light.
