"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.
Let the soul banish all that disturbs; and let the body that envelops it be still, and all the fretting of the body, and all that surrounds it; let earth and sea and air be still; and heaven itself. And then feel the Spirit streaming, pouring, rushing into you from all sides, while you are quiet in this Peace.
