I was reading an article about Merkaba and it says:
A merkaba is a star tetrahedron, a three dimensional 8 pointed star made from two triangular pyramids, one pointing up and the other down. The male pyramid points upwards and begins at your knees, extending several feet above your head. The female pyramid extends downwards from your shoulders and reaches several feet below your own feet.
My question: Is this the same thing that we refer to as Sri Yantra?
