All of us are solitaries: we are born alone through the birth canal into the world and time, and we die alone. No one can enter our interior experience, or its continuum with the outer world we call community. Solitude is the human condition, the universal vocation to be human. It is the willingness, with Love indwelling, to go to the heart of pain to find new life and share it with the world even though you may be separated from it physically. It is from this commitment to be focused through the narrow gate of solitude that self-emptying love is outpoured, and the heart of the community, the heart of its pain, is transformed into the heart of joy.
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.
