“only those people who are capable of being alone are capable of love, of sharing, of going into the deepest core of the other person—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other. They allow the other absolute freedom, because they know that if the other leaves, they will be as happy as they are now. Their happiness cannot be taken by the other, because it is not give by the other.”
