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. In this sense, it is a visual expression of the connections life weaves through all sentient beings, believed to contain a type of Akashic Record of basic information of all living things.
The Tree of life: In Hebrew, it is a mystical symbol within the Kabbalah of esoteric Judaism used to describe the path to God. It is an arrangement of ten interconnected spheres (called sephiroth, meaning 'spheres'), which represent the central organizational system of the Jewish Kabbalistic tradition or 'cosmology' of the Kabbalah.
