Historically it is said that the original discus used by the ancient Greeks in their Olympics was in fact a fossilized ammonite. In India, ammonite fossils are identified with the god Vishnu and are used in ceremonies. Many are collected in Nepal, from the bed of the River Gandaki. These fossils are known as "shaligram shila". The word ammonite is derived from Ammon, an Egyptian god who took the form of a ram. Ammonites are similar in appearance to a ram's horn.
Ammonite and nautiloid fossils have been prized from antiquity for their logarithmic spiral. About the Nautilus Spiral in Sacred Geometry:
The main feature of the Nautilus is the large snail-like shell that is coiled upwards and lined with mother-of-pearl. The shell is subdivided into as many as 30 chambers. As the shell grows, its body moves forward into the new larger chamber and produces a wall to seal off the older chambers. The empty chambers are used to regulate buoyancy. A cross-section of the shell of the Nautilus will show the cycles of its growth as a series of chambers arranged in a precise Golden Mean spiral.
The Golden Mean is represented by the Greek letter phi, (with the decimal representation of 1.6180...) is one of those mysterious natural numbers that seems to arise out of the basic structure of our cosmos. Phi appears regularly in the realm of things that grow and unfold in steps just as the Nautilus shell grows larger on each spiral by phi.
With each revolution completing a cycle of evolution, the Golden Mean Spiral is symbolic of life’s unfolding mysteries. The continuous curves of the spirals, which are feminine in nature, and the ratios between each of the chambers reveal the intimate relationship between the harmonics of nature and Sacred Geometry.
Sacred Geometry is a term used to describe the basic building blocks of the universe. This ancient science explores and explains the physical and energy patterns that create and unify all things and reveals the way that the Universe of creation organizes itself. Every natural pattern of growth or movement conforms inevitably to one or more geometric shapes. From the molecules of our DNA to the galaxy we spiral within, life and it's forms emerge out of geometric codes.
The earliest known proprietors of Sacred Geometry were the Egyptians who embedded its secrets in the ground plans of their temples, their frescoes and in the Giza pyramid. Although these enlightened people used geometry for terrestrial applications, hence the word 'geo-metry' or 'measure of the earth', the aim was metaphysical in nature.
Sacred Geometry reflects the universe, its pure forms and the dynamic relationship of our selves to nature -- the inseparable relationship of the part to the whole. By studying the Sacred Geometry of one thing we give meaning and structural insight into the workings of the inner self. As the renowned geometer Robert Lawlor observes, "The implicit goal of this education was to enable the mind to become a channel through which the 'earth' (the level of manifested form) could receive the abstract, cosmic life of the heavens. The practice of geometry was an approach to the way in which the universe is ordered and sustained. Geometric diagrams can be contemplated as still moments revealing a continuous, timeless, universal action generally hidden from our sensory perception. Thus a seemingly common mathematical activity can become a discipline for intellectual and spiritual insight.

In Hindu religion they are held sacred as saligram, a reminder of the unfolding of the universe by Lord Vishnu the creator. Its spiral shape symbolizes continual change and evolution. Ammonites have absorbed cosmic energy over eons of time and help to stimulate the life force (Chi) within. The Ammonite is also put in the home to attract health, prosperity and success. The Ammonite draws off negative energies like a filter, drawing in stagnant energies and moving them through the spirals then releasing them as fresh, positive, loving life force energies. Ammonite is a stone of protection. It provides for insight and it helps to assist one in seeing the ‘entire picture.’ Meditation with the Root Chakra, encourages ones survival instincts and grounding.
