As has been stated before, 6 is the Sephiroth-(circle) of Tiphareth, which represents the Full Harmonious embellishment of the Energy of the Element, i.e. Beauty in the Element of Earth.. This card shows even greater embellishment because the Moon is in Taurus----which is where the Moon is most exalted, and therefore the Moon is in its highest form and adds the illusion of brilliance; However, the Moon is in transient, so the approach to perfection is not for long.
When viewing this Thoth Deck Card, one can see that the Disks are arranged in a Hexagram as a skeletal format. The Center of the illustration glows with the light glowing of the rose madder of dawn surrounded by three concentric circles of golden yellow, salmon pink, and amber. (due to processing fade these colors are very light). These colors represent Tiphareth (Beauty) fully realized on earth. The planetary signs are arranged in their normal attribution but they are shown as disks irradiated by the central Sun which is idolized as the Rose and Cross. The rose has 49 petals, which is the interplay of 7 with 7. Seven rayed stars are the Symbol of the Great Mother Goddess, as is the Moon. Upon investigation, one will find that the Male electric force and the Female magnetic force are never separate even though upon first glance they appear to be so.
When thrown during a reading, the Six of Disks (Pentacles- in Golden Dawn and Rider-Waite decks) means success in material things has been achieved for the past 6 weeks or 6 months, or will be seen in the next 6 weeks or 6 months. Also, prosperity in business, success, gain, , power, influence, rank,nobility and rule over people----in material undertakings. Fortunate,successful, just and liberal.
If ill dignified by the surrounding cards; purse-proud, insolent from success or even prodigal. As you may note, The Six of Disks-Success, is because of labor on the part of the individual and is thus earned and not a gift; However, like attracts like so in the next 6 weeks or 6 months gifts may appear. With the Moon who is "Priestess of Illusion" so prominent in this card, it is appropriate to understand that material success alone is an illusion of success. Spiritual Manifestation (which we are) is only Successful when The I AM ME, our trinity, is in balanced communion of correspondence. When the "As above is so below" and where value is known as Presence and not material gain.
