Spiritual hunger is a living, radiant fire put by God into hearts so that the ego can be burned; when it has been burned, this fire becomes the fire of longing, which never dies, either in this world or the next. There is no quicker way to God than spiritual hunger; if it travels through solid rock, water gushes forth. Spiritual hunger is essential for the Sufis; it is the showering of God's mercy on them.
"Live up to the light that you have and more will be given to you" is a familiar Quaker saying. Indifference and inattentiveness dim the light, overzealousness causes it to flicker. William Penn warned against "running before we are sent." We can seldom be absolutely sure that we are following the light: psychology has taught us that the voice of the unconscious self may take on a spurious resemblance to a divine call. We can only do the best we know at the time and trust that the Spirit, the Eternal Goodness, Reality, The Christ Within, God -- the name seems to me to matter little -- may be able to make use of the willingness alone, as if just wishing to be sensitive to the light removed some obstacle to the movement of the divine in human affairs.
