Although the process with rainwater—to which the wet way is best applied—is somewhat lengthy at first, consider how much longer some have spent entirely in vain on other materials. Finally, I cannot refrain from adding this further reminder: whoever cannot grasp what I have communicated through diligent reading and reflection should keep his hands away from the fire and consider that God has not appointed him to this work.

Lastly, I commend the seal of silence to everyone who attains this arcanum, so that such a lofty gift of God is not deliberately placed in unworthy hands and made an occasion for utterly indefensible abuse, and so that its possessor does not put himself in danger, as may be gathered from the example I cited in chapter nine.

Above all, I warn anyone pursuing this art who does not intend to use it chiefly for God’s honour, the defence of the Christian faith, and the relief of poor and suffering Christians, but rather to satisfy avarice or indulge pride and licence, to desist. Such a person will attain no happy end; or, if success does occur by the Most High’s permission, the curse and punishment of the righteous God will fall upon him, according to Hollandus’s prophecy. To the triune God be praise, honour, glory, and thanks once again, from eternity to eternity. Amen!
