what mean "twin soul" ?

Question

I have seen somewhere that we all have one twin soul....but what is ?

Answer 1

This means basically the same as soul mate. The origins of this idea can be seen in Greek mythology, and in some eastern philosophies. The basic idea is that a human soul is split in half in some fashion, and each half seeks the other. In Greek mythology, Zeus split the human soul because he feared the power of whole human beings. Plato used this story to explain the nature of love – seeking our other half so that we can be complete.

Answer 2

A twin soul is someone that has the same likes and dislikes as you.
