Flower of Life / Tree of Life
The Flower of Life is the modern name given to a geometrical figure composed of multiple evenly-spaced, overlapping circles, that are arranged so that they form a flower-like pattern with a sixfold symmetry like a hexagon. The center of each circle is on the circumference of six surrounding circles of the same diameter. It is considered by some to be a symbol of sacred geometry, said to contain ancient, religious value depicting the fundamental forms of space and time.
The symbol of the Tree of Life may be derived from the Flower of Life. It is a mystical concept, a metaphor for common descent, and a motif in various world theologies and philosophies. This mystical concept has historically been adopted by some Christians, Jews, Hermeticists, and pagans. Along with the Seed of Life it is believed to be part of the geometry that parallels the cycle of the fruit tree. This relationship is implied when these two forms are superimposed upon each other.
The Tree of Life is most widely recognized as a mystical concept within the Kabbalah, which is used to understand the nature of God and the manner in which He created the world ex nihilo (out of nothing). The Kabbalists developed this concept into a full model of reality, using the tree to depict a "map" of creation. The tree of life has been called the "cosmology" of the Kabbalah.
