Love is the only way to grasp another human being in the innermost core of his personality. No one can become fully aware of the very essence of another human being unless he loves her.
By his love he is enabled to see the essential traits and features in the beloved person; and even more, he sees that which is potential in her, which is not yet actualized but ought to be.
Furthermore, by his love, the loving person enables the beloved to actualize these potentialities. By making him aware of what he can be and of what he should become, he makes these potentialities come true.
