The Merkaba is the subtle body's energy configuration, creating energy fields on the dense, subtle, and mental planes.
It is customary to call the Merkaba construction consisting of two tetrahedra joined together.

At its core, the Merkaba is a powerful energy field of Light that surrounds a person's physical body.
According to one version, the upward tetrahedron is solar, and the downward one is the earth tetrahedron (another option that the downward tetrahedron is called lunar).
According to another version, the upward tetrahedron is the male tetrahedron, and the downward one is the female tetrahedron.

One of the spiritual schools gives the following description: "A human Merkaba is an interaction between three bodies: physical, astral and mental. The physical body is the role of the stator. The upward tetrahedron should rotate clockwise; the downward tetrahedron should rotate counterclockwise. At a certain speed of rotation of thin bodies called critical, the field around a person turns into a crystal called an activated Merkaba. If in this state, a person is activated beyond his ability and he owns the knowledge of subtle plans, then with the help of his Merkaba, he can work wonders - move through space, fly in the air, move into parallel worlds, fly to other planets in subtle bodies, etc."
Of course, to believe in this statement is not easy; it is even more difficult to verify or obtain scientific evidence. Citing such a point of view, we want to tell you that the stellated octahedron is more than a geometric body for some people.
