Hope is the realization of the inner connectedness of all things; of your life and your daily activity with the cosmic scheme of things. The awareness of who you are, that you are the self--that gives you hope. Faith and hope stem from the same inner, intuitive realization of who you are, that you are here for a purpose and that nothing on earth can shake that.
"Contemplating is receiving." (St. John of the Cross) What we receive in prayer is the Spirit, who makes all creation new, moment by moment. It is the Spirit who rebirths us within the caves of our hearts. The case is a metaphor for this silent withdrawal, this going away to be alone, to listen, to gestate the Spirit, to rebirth ourselves. The reborn self is the child of wisdom born in solitude.
