The Flower of Life  The Flower of Life is the modern name given to a geometrical figure composed of multiple evenlyspaced, overlapping circles. They are arranged to form a flowerlike pattern with a sixfold symmetry, similar to 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.
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.

Fibonacci Spiral  In contrast to the golden mean (which has no beginning and no end) the Fibonacci spiralhas a definite beginning but not necessarily an end. Once begun, the Fibonacci spiral cancontinue on into infinity.
The Fibonacci sequence possesses a unique property. Different from the Golden Mean, theFibonacci begins at 0 or 1 but quickly approximates the Golden Mean with ever increasingaccuracy. The Fibonacci sequence seems to be strongly attracted to the Golden Mean Sequence(phi ratio) and attempts to approximate the phi ratio (1.6180339…). 
The Golden Ratio or Golden Mean  In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one.
At least since the 20th century, many artists and architects have proportioned their works to approximate the golden ratio  especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio  believing this proportion to be aesthetically pleasing (see Applications and observations below). A golden rectangle can be cut into a square and a smaller rectangle with the same aspect ratio. Mathematicians since Euclid have studied the golden ratio because of its unique and interesting properties. The golden ratio is also used in the analysis of financial markets, in strategies such as Fibonacci retracement. 
The vesica piscis is a shape that is the intersection of two circles with the same radius, intersecting in such a way that the center of each circle lies on the circumference of the other. The name literally means the "bladder of a fish" in Latin.
The Vesica Piscis is also used as proportioning system in architecture, in particular Gothic architecture.
In Christian art, some aureolas are in the shape of a vertically oriented vesica piscis, and the seals of ecclesiastical organizations can be enclosed within a vertically oriented vesica piscis.
The vesica piscis has been the subject of mystical speculation at several periods of history, and is viewed as important in some forms of Kabbalah. More recently, numerous New Age authors have interpreted it as a yonic symbol and claimed that this, a reference to the female genitals, is a traditional interpretation.

Symbol of the Holy Trinity (also called Triquetra) The doctrine of the Trinity defines God as three divine persons, the Father, the Son (Jesus Christ), and the Holy Spirit. The three persons are distinct yet coexist in unity, and are coequal, coeternal and consubstantial. Put another way, the three persons of the Trinity are of one being. The Trinity is considered to be a mystery of Christian faith.
