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.
Material progress and a higher standard of living bring us greater comfort and health, but do not lead to a transformation of the mind, which is the only thing capable of providing lasting peace. Profound happiness, unlike fleeting pleasures, is spiritual in nature. It depends on the happiness of others and it is based on love and affection.
The way of love is as true as the way of knowledge. All paths ultimately lead to the same Truth. But as long as God keeps the feeling of ego in us, it is easier to follow the path of love.
Far better is it to dare mighty things, to win glorious triumphs, even though checkered by failure... than to rank with those poor spirits who neither enjoy nor suffer much, because they live in a gray twilight that knows not victory nor defeat.
