Fibonacci Numbers: a sequence of numbers where each number is the sum of the two numbers before it. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89... below is a drawing of the sequence: notice how squares are added on to form rectangles.  Fibonacci numbers are often used in computer algorithms.  They also appear in biological settings, branching in trees, the arrangement of leaves on a stem, the fruit sprouts of a pineapple, the flowering of an artichoke, an uncurling fern and the arrangement of a pine cone's bracts.

The 'Flower of Life' is a geometrical shape composed of multiple evenly-spaced, overlapping circles arranged in a flower like pattern with six fold symmetry like a hexagon. Its perfect form, proportion and harmony has been known to philosophers, architects and artist around the world. Pagans consider it sacred geometry containing ancient religious value depicting the fundamental forms of space and time. It is believed to contain a record of basic information of all living things and is the visual expression of the connections of life that run through all sentient beings.  The Egg of Life is said to be the shape of a multi-cellular embryo in its first hours of creation.

Metatron's cube depicts the five platonic solids which may be derived form the flower of life. The five platonic solids are geometrical forms which are said to act as a template from which all life springs, according to spiritual belief. The Platonic solids are five structures that are crucial because they are the building blocks of organic life. These five structures are found in minerals, animated and organic life forms, sound, music, language, etc. 

The 'Seed of Life' is formed from seven circles being placed with sixfold symmetry, forming a pattern of circles and lenses, which acts as a basic component of the Flower of Life's design.

The 'Fruit of Life' symbol is composed of 13 circles taken from the design of the Flower of Life. It is said to be the blueprint of the universe, containing the basis for the design of every atom, molecular structure, life form, and everything in existence. It contains the geometric basis for the delineation of Metatron's Cube, which brings forth the platonic solids.

Examples of the flower of life, the golden ratio, and the Fibonacci Numbers can be found throughout many great works or art, architecture, and music.
