Sacred geometry involves sacred universal patterns used in the design of everything in world around us, most often seen in sacred architecture and sacred art. The basic belief is that geometry and mathematical ratios, harmonics and proportion are also found in music, light, cosmology. This value system is seen as widespread even in prehistory, a cultural universal of the human condition.
It is considered foundational to building sacred structures such as temples, mosques, megaliths, monuments and churches; sacred spaces such as altars, temenoi and tabernacles; meeting places such as sacred groves, village greens and holy wells and the creation of religious art, iconography and using "divine" proportions. Alternatively, sacred geometry based arts may be ephemeral, such as visualization, sand painting and medicine wheels.
Sacred geometry may be understood as a worldview of pattern recognition, a complex system of religious symbols and structures involving space, time and form. According to this view the basic patterns of existence are perceived as sacred. By connecting with these, a believer contemplates the Great Mysteries, and the Great Design. By studying the nature of these patterns, forms and relationships and their connections, insight may be gained into the mysteries - the laws and lore of the Universe. Such contemplation can be used as basis for meditation.
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's been used in design, architecture and art,
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.
There are many spiritual beliefs associated with the Flower of Life; for example, depictions of the five Platonic Solids are found within the symbol of Metatron's Cube, which may be derived from the Flower of Life pattern. These platonic solids are geometrical forms which are said to act as a template from which all life springs.
Another notable example of that which may be derived from the Flower of Life is the Tree of Life. This has been an important symbol of sacred geometry for many people from various religious backgrounds. Particularly, the teachings of the Kabbalah have dealt intricately with the Tree of Life.
