The 9 of Wands, is Yesod in Aziluth; it is The Lord of Great Strength. It's Planet is the Moon and the sign is Sagittarius.
Angels of the Decan are: Yirthiel, and Sahiah.
The 9 of Wands-Strength, is the influence of Yesod in the World of pure spirit. The Lunar powers do acquire great strength in Sagittarius, but being the Moon, there are two sides to this "coin". Meaning, that successes are usually acquired by strife, apprehension and moments of insecurity.[illustration of Four Worlds, from the book: THE QABALISTIC TAROT, by Robert Wang]
The good health and strength of this card is certain, but it harbors doubt about the later course it may take. It is best to know the aphorism: "Change is Stability", when viewing this card.
The Nines may be considered the best that can be obtained from the type of forces involved, when regarded from a practical- material standpoint.
The Thoth Deck 9 of Wands, shows 8 background Wands as Arrows (Sagittarius influence) and one Master Arrow in the forefront, sporting a Sun at one end as a driving force, and a Moon at the other end as it's point. This implies that Sagittarius joins the Sun and the Moon, and that the Greatest Strength is the Balance of this coupling flow. The flow of Electric Male and Magnetic Female receptivity. Together, all that is Living Form, is from this flow and reception. When we, as Magi, master both the Male Force and the Female force within,it is called a "Oneness" and it reveals all the 4 Worlds in a communion of the Sun (Father) and the Moon (Mother) that never ceases. The Tenfold flames of the card, imply that the Energy of the Solar Logos, is directed down ward into the "reflection of being'.
When this card is thrown during a reading, it implies internal strength, recovery from illness, potency and spiritual force. Yet, it is Moon in Yesod, so one may have to defend their ideas, but because of Sagittarius, will not lack the strength to do so. The 9 of Wands also implies that energy is brought back into balance, thus health restored.
Creatively, this card implies a peek experience in ability were one sees clearly and accurately, leading to solid creations that will have the strength to endure over time. Here the Energy of the Spirit is rapid , interchanging both electric and magnetic energy, taking whatever action is necessary to restore balance and thus enable the Mind. (Moon is ruler of the Sub-conscious).
