This is the 8 pointed Tantric Star. It is one of the Crystalline Light Body Shapes. It is basically a stellated Octahedron or you can think of it as a Star Tetrahedron with an Octahedron in the center. The Tantric Star is formed by interlocking ascending and descending tetrahedrons. Also known as the Mer Ka Ba, the Tantric Star functions as a 3-dimensional mandala, connecting us to our centre point, a stargate into the matrix of manifest reality. It describes the energy pattern created by the electromagnetic male and female potencies of creation as they come together to conceive atoms, Humans, the Universe - the seminal form that Consciousness takes as it initiates the polarization of the Monad into the sacred enclosure of the Trinity, holding the frequency of the 3rd dimension fully manifest in form.
