The mind is to be a reservoir of Light — free, ready to give color and form, ready to speak from Wisdom's Source. Silence is the opening note. The Indwelling Light illumines the heart and mind, loosening the sightless, stormswept self. The freeing of Light, of God's own Life within, is the means of self-expression — not self-filled expression — but God-like freedom.
But it's actually, spiritually speaking, in the opposite direction. It's in the leaning into the conditions that you at first experience as intolerable, that you gradually realize that they are exactly the conditions that bring forth something new, something that can't be born forth in any other way.
