What is a Merkabahs/merkaba?

Question

I wanted to buy a crystal in the shape of a merkaba. But I don't know what a merkaba is, and I don't want to wear something when I don't know the meaning. So could someone please fill me in? Thx

Answer 1

In modern esoteric teachings, it is taught that the MerKaBa is an interdimensional vehicle consisting of two equally sized, interlocked tetrahedra of light with a common center, where one tetrahedron points up and the other down. This point symmetric form is called a stella octangula or stellated octahedron which can also be obtained by extending the faces of a regular octahedron until they intersect again.

In his books, researcher and physicist Drunvalo Melchizedek describes this figure as a "Star Tetrahedron", since it can be viewed as a three dimensional Star of David. By imagining two superimposed "Star Tetrahedrons" as counterrotating [1], along with specific "prana" breathing techniques, certain eye movements and mudras, it is taught that one can activate a non-visible 'saucer' shaped energy field around the human body that is anchored at the base of the spine. Depending on the height of the person doing the exercise, this field is about 55 feet across. Once activated, this 'saucer' shaped field is capable of carrying ones consciousness directly to higher dimensions

Answer 2

A merkaba looks like a 3D star of David. It is composed of two tetrahedrons, one pointing up and one pointing down, which interlock. It is one of the shapes of our spinning energetic fields.
I am curious why you want to buy/wear a symbol when you have no knowledge of it.
