He made the letter Vav king over thought, and He bound a crown to it, and He combined one with another, and with them He formed Taurus in the universe, Iyar in the year, and the right kidney in the soul (person), male and female.
He made the letter Zayin king over motion, and He bound a crown to it, and He combined one with another, and with them He formed Gemini in the universe, Sivan in the year, and the left foot in the soul (person), male and female.
The letter Hey represents the path connecting Keter with Chokmah. Since Hey is a king over speech, this reminds us that the creation of the universe began with speech, "and God said . . .". In Pirkei Avot, Chapter 5, we read, "With ten divine utterances was the world created." Thus, we have a suggestion here that when we wish to take charge of our lives, we might begin by vocalizing our intentions. A remnant of the power of speech is found in the word 'abracadabra' which is a corruption of an Aramaic phrase stating, "I create it as I speak it."
The letter Vav represents the connective "and" in Hebrew, and it is assigned to the path connecting Binah with Keter in the Tree of Life. Vav is the king over thought. In our minds, 'thought' is the link between the world of form and the formless awareness that is witness to all we know. When we realize the impossibility of separting the Knower from the Known and the Act of Knowing, then form and formlessness become One.
The letter Zayin, the king over motion, is the seventh letter in the aleph-bet and is the connecting path between Gevurah (strength) and Chokmah (wisdom) on the Tree of Life. As the seventh letter, it represents the Sabbath, but since this letter is shaped like a sword, it also represents strife. When we cease from motion and find the stillness within, we experience the peace of Shabbat. However, when we are swept away by the world of motion, then our lives are caught up in strife.
