The world is like a circle, with God as eternal creator in the centre. Everything that is in it is like a radius travelling towards God, Who gives existence. In the centre, they’re perfectly united, but just a short distance away from it they’re separated. The greater the distance from the centre, the greater their separation; and the closer they are to the centre, the more they’re united to it and to one another.
True unity, true contact between two beings can be realized only through God. There’s no direct path which links two different beings. Unification comes only through God.
