"32 paths of secret wisdom"
Tree of Life is one of the most recognized symbols of sacred geometry. The structure of the Tree of Life is connected to the sacred teachings of the Jewish Kabbalah but can be seen in other traditions as well, such as the ancient Egyptian tradition.
The Tree of Life is explained in Sefer Yetzira ("Book of Creation"). The book explained the creation as a process involving the 10 divine numbers (sefirot) of God the Creator and the 22 letters of the Hebrew alphabet. The 10 sefirot together with the 22 letters constitute the "32 paths of secret wisdom".
The Tree of Life pendant forms the key to God's original creation. The pendant fits exactly to the Seed of Life and the Flower of Life.
The Tree of Life is used as a sign of unity and love.
