The shape of the pyramid is found over the course of history in several civilizations and holds many different spiritual meanings. The pyramid is called a Tetrahedron in Sacred Geometry, and its main function is assisting with manifestation. The cool thing about this shape is the contrasting yet harmonious output of energy that is at work within the shape. The solid structure base, much like a cube, has a very grounded and stabilized energy, while still allowing energy to directly flow out of the point. Pyramids connect energy from the crown chakra to the root chakra, allowing us to feel in tune with higher dimensional thinking/our higher selves while still staying grounded to Earth.
