The hardest thing in life may be to learn to truly trust that there is something noble and generative in ourselves. This is a greater sense of the notion of believing in our self; to truly believe in oneself means to uncover the inner core of imagination and authenticity that can also be called the genius within us. When we connect to the inner resident of the soul, we also learn how we are woven to the Soul of the World.
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.
