The number Ten, Malkuth, as always, represents the final issue of the Energy. Here is great and final solidification. The force is completely expended and results in death. Mercury rules this card in Virgo; and this may imply that the acquired wealth, being inert, will be dissipated unless put to further use by devoting its power to objects other than mere accumulation.
The disks, or (as they have now become) coins, are arranged on the Tree of Life, but the Tenth coin is much larger than the rest; the image indicates the futility of material gain.
These disks are inscribed with various symbols of mercurial character except that the coin in the place of Hod (Mercury) on the Tree is marked with the cipher of the Sun. This indicates the only possibility of issue from the impasse produced by the exhaustion of all the elemental forces. At the end of matter must be complete stagnation, were it not that in it is always inherent the Will of the Father, the Great Architect, the Great Arithmetician, the Great Geometer. In this case, then, Mercury will represent the Logos, the Word, the Will, the Wisdom, the Eternal Son, and Virgo the Virgin, in every implication of that symbol. This card is in fact a hieroglyph of the cycle of regeneration.
Among the Geomantic figures, Mercury in Virgo is Conjunctio. The meaning, conjunction, is shown plainly by the attraction of the descending (female) Triangle, the cipher of the Yoni, to the ascending (male) Triangle, that of the Lingam. This union completed, they appear interlaced, forming the figure of Capricornus, the Sign in which the Sun finds his rebirth. It is the holy Hexagram, the symbol of the uniting of the Macrocosm and the Microcosm, the accomplishment of the Great Work, the Summum Bonum, True Wisdom and Perfect Happiness. Sic sit vobis!
