"Consider gold: the oftener it is melted, the more pure does it become; continue to melt it and every imperfection is destroyed. This is the effect of fire on all materials. The soul, however, cannot be annihilated in God, but in herself she can, and the longer her purification lasts, the more perfectly does she die to herself, until at length she remains purified in God.
When gold has been completely freed from dross, no fire, however great, has any further action on it, for nothing but its imperfections can be consumed. So it is with the divine fire in the soul.
God retains her in these flames until every stain is burned away, and she is brought to the highest perfection of which she is capable, each soul in her own degree. And when this is accomplished, she rests wholly in God. Nothing of herself remains, and God is her entire being.
When he has thus led her to himself and purified her, she is no longer passable, for nothing remains to be consumed. If when thus refined she should again approach the fire she would feel no pain, for to her it has become the fire of divine love, which is life eternal and which nothing mars."
