This is a Flower of Life Chakras crystal grid made out of Birch wood. These are approximately 9 inches in diameter and 1/4" thick. This is just for the grid, stones much be purchased separately. 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. Chakra meaning "wheel, circle", sometimes spelled Cakra or Cakka, is any center of subtle body believed to be a psychic-energy center in the esoteric traditions of Indian religions. The concept is found particularly in the tantric traditions of Hinduism, Buddhism and Jainism Crystal grid and healing sets are groups of stones that go together for a purpose. Sets of crystals and stones are used for ritual magickal or spiritual crystal healing purposes or with Reiki-Seichim energy work for healing. Some are generalized and others have specific purposes.
