I may say that B-love, in a profound but testable sense, creates the partner. It gives him a self-image, it gives him self- acceptance, a feeling of love-worthiness, all of which permit him to grow. It is a real question whether the full development of the human being is possible without it.
In fact the whole passion ordinarily termed love (and heaven help me if I can think of any other term to apply to it) is of such exceeding triviality that I see nothing that I think comparable with it.
It is wrong to think that love comes from long companionship and persevering courtship. Love is the offspring of spiritual affinity and unless that affinity is created in a moment, it will not be created for years or even generations.
True love in this differs from gold and clay, that to divide is not to take away. Love is like understanding, that grows bright, gazing on many truths.
