The smile of the contemplative in the presence of the Beloved is merely a physical expression of the total joy one perceives as one communes with God. St. Bernard used to say, "The joy of being in love is in the very loving." In other words, joy is not to be sought for itself, but is a by-product of love, and the smile is but the physical, exterior expression of the inner joy-love.
Some centuries ago Joachim of Flores prophesied that there would be in the future a new age that would be the Age of the Holy Spirit. This is Sophia's age, in which She declares: Omnia coniungo ("I unite all things"). Sophia the God-bearer, becomes the "inner mother to the Divine Child, the incarnating Self within us", enabling us to be born again, through the Spirit, in the world. And in this new world, Sophia helps us to see in the geometrical forms of Nature, the natural shapes of the human soul.
