Sacred geometry was (and to many still is) the blueprint of creation, the origin of form. It is the language of the creator, a language that was before all else and reveals the way in which creation and energy was organised, and it shows itself in the form of geometrical shapes; circles, triangles, squares...
These shapes can be seen throughout many forms of nature; the intricate pattern of a single snowflake, the molecules of our DNA, the spirals on snails shells, the complexities within a bee hive, the orbital patterns and distances of planets, spiralling galaxies, the air we breathe... all life was created from this geometric code and ancient architects calculated these harmonious patterns, shapes and distances and applied them within their constructions.
The ancient Greeks dedicated vast amounts of time in understanding these mathematical relationships; the golden ratio (golden mean or golden section or divine proportion) is one result of this work. Throughout the centuries artists and architects have studied and utilised its dimensions to enable their work to become more aesthetically pleasing and achieve a positive effect on the human psyche.
Sacred Geometry can also be heard. There is a reason why certain notes in music sound harmonious while others sound out of place. Within sound vibrations are complex mathematical relationships and patterns which relate to one another and determine a positive or negative influence within us. These complex mathematics/specific dimensions were implemented within ancient temples to acheive divine resonance.
