The Merkaba is an extremely powerful symbol. It is a combination of two star tetrahedrons - one pointing up to the heavens, channelling energy down from the Universe to the earth plain, and one pointing downwards, drawing energy up from the earth beneath. The top, or upward pointing tetrahedron is male and rotates clockwise, with the bottom or downwards pointing one being female, which rotates counter clockwise.
