Is that specific person in your life a soul mate? Or a twin flame? How do you know the difference? Some use the words interchangeably but the most important thing is to not over rationalize if the person is a mate or a flame.
Fill each other’s cup, but drink not from one cup.
Give one another of your bread, but eat not from the same loaf.
Sing and dance together and be joyous,
but let each one of you be alone,
Even as the strings of a lute are alone
though they quiver with the same music.
Give your hearts, but not into each other’s keeping;
For only the hand of Life can contain your hearts.
And stand together yet not too near together;
For the pillars of the temple stand apart,
And the oak tree and the cypress grow not in each other’s shadow.
~ Khalil Gibran
