(12) Understand rightly the Manner of the Existence of this Mercurius. The Word M E R, is first the strong, tart, harsh Attraction; for in that Word (or Syllable Mer) expressed by the Tongue, you understand that it jars [proceeding] from the Harshness, and you understand also, that the bitter Sting or Prickle is in it; for the Word M E R is harsh and trembling, and every Word [or Syllable] is formed or framed from its Power or Virtue, and expresses whatsoever the Power or Virtue does or suffers. You [may] understand that the word [or syllable] C U, is [or signifies] the Rubbing or Unquietness of the Sting or Prickle, which makes that the Harshness is not at Peace, but heaves and rises up; for that Syllable [thrusts itself or] presses forth with the Virtue [or Breath] from the Heart, out of the Mouth. It is done thus also in the Virtue or Power of the Prima Materia [or first Matter] in the Spirit, but the syllable C U having so strong a Pressure from the Heart, and yet is so presently snatched up by the Syllable R I, and the whole Understanding [Sense or Meaning] is changed into it, this signifies and is the bitter prickly Wheel in the generating, which vexes and whirls itself as swiftly as a Thought: The Syllable U S is [or signifies] the swift Fire-flash, that the Materia, or Matter, kindles in the fierce Whirling between the Harshness and the Bitterness in the swift wheel; where you may very plainly understand [or observe] in the Word, how the Harshness is terrified, and how the Power or Virtue in the Word sinks down, or falls back again upon the Heart, and becomes very feeble and thin: Yet the Sting or Prickle with the whirling Wheel, continues in the Flash, and goes forth through the Teeth out of the Mouth; where then the Spirit hisses like a Fire in its kindling, and returning back again strengthens itself in the Word. mark.

(9) For the Harshness is as hard as a Stone [or Flint,] and the Bitterness rushes and rages like a P breaking Wheel, which breaks the Hardness, and stirs up the Fire, so that all comes to be a terrible Crack of Fire, and flies up; and the Harshness or Astringency breaks in Pieces, whereby the dark Tartness is terrified and sinks back, and becomes as it were feeble or weak, or as if it were killed and dead, and runs out, becomes thin, and yields itself to be overcome: But when the strong Flash of Fire shines back again upon or into the Tartness, and is mingled therein, and finds the Harshness so thin and overcome, then it is much more terrified; for it is as if Water was thrown upon the Fire, which makes a Crack: Yet when the Crack or Terror is thus made in the overcome Harshness, thereby it gets another Source, [Condition or Property,] and a Crack, or Noise of great Joy proceeds out of the wrathful Fierceness, and rises up in fierce Strength, as a kindled Light: For the Crack in the Twinkling of an Eye becomes white, clear, and light; for thus the Kindling of the Light comes in that very Moment as soon as the Light (that is, the new Crack of the Fire) is infected or impregnated with the Harshness, the Tartness or Astringency kindles, and shrieks, or is affrighted by the great Light that comes into it in the Twinkling of an Eye, as if it did awake from Death, and becomes soft or tmeek, lively and joyful; it presently loses its dark, rough, harsh, and cold Virtue, and leaps or springs up for Joy, and rejoices in the Light; and its Sting or Prickle, which is the Bitterness, that triumphs in the turning Wheel for great Joy.
