See, thou beloved Soul, thou wast gone out from God; but his Love caught hold of thee again, and P fastened thee (with the Promise) to his Thread; and then came the Fulfilling of the Promise, and put another new Body on to thee; but thou canst not have another Soul, for thy Soul was out of the Eternity. Therefore now as the Holy Ghost overshadowed and filled [or impregnated] Mary, so the Water out of the Heavenly Matrix (which has its Beginning out of the Trinity) in the Baptism of Christ (and in all baptized Christians) overshadowed and filled the Soul of Christ in the Baptism in Jordan, and also the Souls of all Christians, and so renewed the earthly Water (of the Out-Birth) in the Soul, and washed it clean, that it is rin itself a pure Angel, which of itself may eat of the heavenly Fruit; and that is the Cause of the Baptism. O Man consider thyself.

So the cleansing of the soul is to recover the freshness of her former nature and to become as she was.
