Important Note: to better understand the contents of this page, I recommend you to read first the page about Sepher Yetzirah and watch its video.
The 11th sign is Aquarius, the last sign of the element Air.
This is the description of Aquarius in the Sepher Yetzirah: “He made the letter Tzadde king over eating, and He bound a crown to it, and He combined one with another, and with them He formed Aquarius in the Universe, Shvat in the Year, and the upper stomach in the Soul male and female.”
The thematic of Aquarius is related to the sense of eating and the upper stomach (qorqeban קורקבן).
The qorqeban is literally the gizzard of birds. If we interpret the meaning in relation to the human being, we can say that the qorqeban is composed by the mouth, the 32 teeth and the esophagus. In other words, the upper part of the digestive system. With the upper stomach we introduce the food in the body.
Kabbalah says that the qorqeban chooses the food. In Kabbalah our relation with the food is a consequence of our wisdom. 32 teeth as the number of the Paths of Wisdom: the 10 Sephiroth and 22 paths of Etz Haim, the Tree of Life.
Aquarius’ thematic is the wisdom. The capacity to have a discerning mind, to understand the good and the evil without any influence.
צ is the letter related to this sign. Tzadde represents the perfect union of the right and left cerebral hemispheres. Thanks to this union, Aquarius may become a Righteous Man, the Tzaddiq, a rhetorical figure which represents the highest level of Aquarius.
The 3 levels of Aquarius, its relation with Tzadde, the sense and the body part are explained in the video.
