Sacred geometry refers to the belief that certain geometric shapes and patterns, such as the circle, the spiral, or more complex forms like the Flower of Life, hold spiritual meaning and reflect the underlying structure of the universe. These patterns are believed to appear repeatedly throughout nature, art, and architecture across many cultures and eras.

In a spiritual context, sacred geometry is sometimes used in meditation, art, or crystal grids, with the belief that specific shapes can help focus or amplify intention during a practice.
