The Merkaba is two things that share one name. In Jewish tradition, the merkavah (Hebrew for "chariot") is the divine throne-chariot seen by the prophet Ezekiel and the centre of an early mystical practice known as Merkabah mysticism. In modern spirituality, the Mer-Ka-Ba is a light body pictured as two interlocking, counter-rotating tetrahedra (a star tetrahedron) around the human form, activated through a seventeen-breath meditation taught by Drunvalo Melchizedek from the 1980s onward.
The two meanings are routinely blended online, which confuses both camps. Skeptics dismiss the whole subject as invented, which ignores a Jewish mystical tradition with a real textual history, and enthusiasts often present the modern meditation as an ancient Egyptian teaching, which the evidence does not support. Knowing which layer comes from where makes the practice easier to understand and easier to discuss honestly. It also explains why the Merkaba sits alongside the Flower of Life and the Emerald Tablets in the material Billy Carson teaches.
What does Merkaba mean?
Merkaba is an English spelling of the Hebrew merkavah, which means "chariot" and comes from the root r-k-b, "to ride". In the Hebrew Bible the word is used for ordinary chariots, and in later Jewish tradition it became the standard name for the throne-chariot of God described in the first chapter of Ezekiel.
The modern spelling "Mer-Ka-Ba", with hyphens, belongs to a different story. In Drunvalo Melchizedek's teaching the word is split into three supposedly Egyptian parts, usually glossed as Mer (light), Ka (spirit) and Ba (body), so that the whole means something like a vehicle of light that carries spirit and body together. That breakdown is a modern folk etymology. The Hebrew word is a single noun with no connection to Egyptian, and the three-part reading has no support in ancient Egyptian texts, as the section on Egypt below explains.
Ezekiel's chariot vision
The original Merkabah is the vision recorded in Ezekiel 1, which the prophet dates to the fifth year of King Jehoiachin's exile, when he was among the Judean captives by the river Chebar in Babylonia.
Ezekiel describes a storm wind from the north, a great cloud and flashing fire. Out of it come four living creatures, each with four faces (a human, a lion, an ox and an eagle) and four wings. Beside them are wheels that gleam like beryl and seem to be built "a wheel within a wheel", their rims full of eyes, moving wherever the spirit of the creatures goes. Above the creatures stretches a firmament like crystal, above that a throne like sapphire, and on the throne a figure with the appearance of a man, surrounded by radiance. Ezekiel's own summary is careful and layered: this was "the appearance of the likeness of the glory of the LORD."
Two details matter for everything that follows. First, the word merkavah does not actually appear in Ezekiel 1; the association is made in later texts such as 1 Chronicles 28:18, which speaks of "the chariot of the cherubim", and the Wisdom of Ben Sira 49:8, which says Ezekiel saw a vision of glory "on the chariot of the cherubim". Second, the vision returns in Ezekiel 10, where the living creatures are identified as cherubim. Later readers treated these chapters as a map for approaching heaven itself.
Merkabah mysticism: the Jewish tradition
Merkabah mysticism is the Jewish contemplative tradition built on Ezekiel's vision, in which the practitioner seeks to ascend through heavenly palaces and behold the divine throne. Its main texts are known as the Hekhalot ("palaces") literature, usually dated between roughly the third and eighth centuries CE, and they include works such as Hekhalot Rabbati, Hekhalot Zutarti, Ma'aseh Merkavah and the book known as 3 Enoch.
These texts describe adepts, oddly called "those who descend to the chariot", passing through seven palaces guarded by angels, using divine names, seals and hymns to proceed safely, and joining the angelic liturgy before the throne. The tradition was treated as dangerous. The Mishnah, in tractate Hagigah 2:1, rules that the "work of the chariot" may not be expounded even to one student unless he is a sage who already understands by his own knowledge. The Babylonian Talmud, Hagigah 14b, tells the story of four rabbis who "entered the orchard" (pardes); of the four, only Rabbi Akiva is said to have entered in peace and left in peace.
The modern study of this material begins with Gershom Scholem, whose Major Trends in Jewish Mysticism (1941) presented Merkabah mysticism as the earliest phase of Jewish mysticism and a forerunner of Kabbalah. Later scholars, including David Halperin and Peter Schäfer, have questioned parts of Scholem's picture, for example how far the texts record actual ecstatic ascents rather than literary and liturgical traditions. What none of this literature contains is a star tetrahedron, a counter-rotating energy field or a breathing technique to spin one. Those belong to the modern layer.
The star tetrahedron: real geometry, modern meaning
The shape now called the Merkaba is the star tetrahedron, a genuine geometric figure formed by two regular tetrahedra interpenetrating, one pointing up and one pointing down. Mathematicians know it as the stella octangula, the name Johannes Kepler gave it in the early seventeenth century.
Its properties are exact and easy to check. The eight points of the compound are the eight corners of a cube, and its twelve edges are the diagonals of that cube's six faces. The space shared by the two tetrahedra is a regular octahedron, and the star tetrahedron is the only stellation of the octahedron, which is why it is also called the stellated octahedron. It appears in Renaissance geometry and is closely related to the Platonic solids that feature in [Flower of Life](/flower-of-life-explained-sacred-geometry-history-and-meaning) diagrams.
What is not ancient is the meaning attached to it. No Jewish, Egyptian or Greek source links the stella octangula to Ezekiel's chariot or to a body of light. That link was made in the twentieth century, most influentially in the Flower of Life teachings. The distinction between the mathematics, which is real, and the symbolism, which is a later layer, runs through all of [sacred geometry](/sacred-geometry-explained-the-shapes-the-history-and-what-is-actually-mathematical).
Where the Mer-Ka-Ba teaching comes from
The modern Mer-Ka-Ba teaching comes from Drunvalo Melchizedek, who taught it in his Flower of Life workshops from the 1980s and later published it in The Ancient Secret of the Flower of Life, volume 1 (1998) and volume 2 (2000). The workshops grew out of the wider 1980s Flower of Life movement, and the books gathered sacred geometry, Egyptian temple lore, Atlantis and the Merkaba into one system.
In that system, every person is said to be surrounded by an energetic star tetrahedron. One tetrahedron is associated with the sun and masculine energy, the other with the earth and feminine energy. When the two fields rotate in opposite directions, the teaching holds, they form a Mer-Ka-Ba: a light body usually visualised as a disc or saucer-shaped field around the practitioner. Melchizedek presented this knowledge as originating with Thoth and ancient Egypt, the same figure at the centre of Maurice Doreal's 1939 [Emerald Tablets of Thoth](/emerald-tablets-of-thoth-explained). That shared attribution is the main reason the Merkaba, the Flower of Life and the Emerald Tablets are now taught together, even though Doreal's text itself does not describe a Mer-Ka-Ba.
Is Mer-Ka-Ba an ancient Egyptian word?
No. Egyptologists know of no ancient Egyptian term "Mer-Ka-Ba", and the word does not appear in any known Egyptian text. The three-part reading was created by combining genuine Egyptian concepts in a way the Egyptians themselves did not.
Two of the parts are real. The ka was the vital force or life-essence of a person, created at birth and sustained after death through offerings; it is written with a hieroglyph of two raised arms. The ba was the aspect of a person that could move between the tomb and the world of the living, often shown as a bird with a human head. Neither word means "body", however; the Egyptian word for the physical body was a different term, khet. The Egyptian word usually transliterated mr does exist, but its best-known meaning is "pyramid", not a kind of light. The honest summary is that the Mer-Ka-Ba borrows authentic Egyptian vocabulary for a modern teaching, and it is best evaluated as a modern teaching.
How the Mer-Ka-Ba meditation works
The Mer-Ka-Ba meditation is a structured breathing and visualisation practice of seventeen breaths, as set out by Drunvalo Melchizedek. It combines rhythmic breathing, hand positions (mudras) and visualisation of the star tetrahedron around the body.
In outline, the sequence has three stages. The first six breaths are framed as clearing and balancing. The middle breaths shift to a smooth, continuous rhythm and build a visualised sphere of energy around the body. The final breaths are used to picture the two tetrahedral fields spinning in opposite directions. The detailed mudras, counts and visualisations are set out in Melchizedek's books, which remain the source for the specific method.
What can be said plainly is that the meditation is a practice of attention, breath and imagery, similar in structure to other guided visualisations. The larger claims made for the light body are claims of the tradition, not tested findings. Readers exploring related practices may also find the site's guide to [third-eye and pineal-gland meditation](/how-to-open-your-third-eye-pineal-gland-meditation) useful, since the two are often practised together.
Billy Carson's reading
Billy Carson treats the Merkaba as a practical spiritual tool rather than an abstract symbol. In his Compendium of the Emerald Tablets (2019), a tablet-by-tablet commentary on Doreal's text, he connects the tablets' language of light, geometry and ascent to the Flower of Life and the Merkaba, reading them as parts of one body of knowledge about consciousness. The book, and the questions readers bring to it, are covered in the site's guide to [the Compendium of the Emerald Tablets](/the-compendium-of-the-emerald-tablets-billy-carsons-book-explained).
Carson also teaches the practice directly. Merkaba work features in his Meditation Monday sessions, and a guided Merkaba meditation led by him is available on his channel. In his framing, the star tetrahedron is a map for focusing attention and intention, and meditation is the way a person moves from reading about consciousness to working with it.
His interpretation stands in a clear lineage: Doreal's 1939 Thoth text, Drunvalo Melchizedek's Flower of Life and Mer-Ka-Ba teachings, and Carson's own synthesis. Placing it in that lineage lets readers see what is ancient (Ezekiel's vision and the Merkabah tradition, the geometry, the Egyptian ka and ba), what is modern (the light-body interpretation and the seventeen-breath method) and what is Carson's own contribution: the way he ties these threads to the Emerald Tablets and to daily practice.

Frequently asked questions
What is the difference between Merkabah and Merkaba?
Merkabah (or merkavah) is the Hebrew word for "chariot" and refers to the divine throne-chariot in Ezekiel 1 and to the Jewish mystical tradition built on it. Merkaba, often written Mer-Ka-Ba, usually refers to the modern light-body teaching and meditation popularised by Drunvalo Melchizedek.
What shape is the Merkaba?
In the modern teaching the Merkaba is a star tetrahedron, two regular tetrahedra interlocked so that one points up and one points down. Geometers call it the stella octangula or stellated octahedron; its eight points are the corners of a cube. In Ezekiel's vision, by contrast, the chariot is described through living creatures, wheels and a throne, not a geometric solid.
Is the Merkaba mentioned in the Bible?
The throne-chariot is described in Ezekiel 1 and 10, although the word merkavah itself is attached to the vision in later texts such as 1 Chronicles 28:18 and the Wisdom of Ben Sira. The star tetrahedron and the light-body meditation do not appear in the Bible.
Who created the Mer-Ka-Ba meditation?
The seventeen-breath Mer-Ka-Ba meditation was taught by Drunvalo Melchizedek in his Flower of Life workshops and published in The Ancient Secret of the Flower of Life (volume 1, 1998; volume 2, 2000). He presented it as knowledge originating with Thoth, but there is no ancient text containing the method. Many teachers, including Billy Carson, now lead their own guided Merkaba meditations.
Is Mer-Ka-Ba an Egyptian word?
No ancient Egyptian word "Mer-Ka-Ba" is known. The ka and ba are genuine Egyptian concepts of the soul, but combining them with mer to mean "light, spirit, body" is a modern interpretation, and neither ka nor ba meant "body" in Egyptian.
