Sacred geometry is the study of geometric shapes and patterns that are believed to have spiritual significance. It often involves shapes like the Flower of Life, Metatron's Cube, and the Golden Ratio, which are thought to represent the fundamental structure of the universe. These shapes are found in nature, art, and architecture, symbolizing harmony and balance. Many cultures, including the Ancient Egyptians and Greeks, have used sacred geometry in their designs and spiritual practices. It is often associated with the idea that certain geometric forms can connect individuals to the divine or the cosmos, promoting a sense of unity and understanding of the world around us.
