Within the Neurohacker Collective logo you’ll notice some familiar shapes and patterns found in sacred geometry, spiritual traditions and of course the NHC initials.
The many elements, such as the Metatron's cube, OmAhOm, the flower of life and transmutation circles that make up elements of the logo have different histories and traditions behind them but also share some similarities such as multiple elements all being connected to one another and the power to focus energy and transform one element into another.
Symbols and Elements:
Metatron’s Cube is composed of 13 spheres held together by lines from the midpoint of each sphere.
The spheres of Metatron’s Cube represent the ‘Feminine’ whilst the straight lines represent the ‘Masculine’. Thus Metatron’s Cube represents the weaving together of the Male & Female polarities to create the ONENESS field of the infinite ALL.
Metatron’s Cube is a sacred Sacred Geometrical symbol that forms a map of Creation and it is this ‘map’ that the mystics, sages and ancient civilizations have revered throughout the ages of time. 
Some ancient traditions claim Metatron was the highest angel. It is also said that Metatron served as a celestial scribe and that he wrote down God’s words. In Egyptian mythology he was Thoth the Scribe. Other traditions and texts claim Metatron was born as a man, Enoch, and ascended to heaven, taken by God. 
Metatron's Cube shares 2-D resonance with the Flower of Life.
The Flower of Life also has thirteen circles. If each circle's center is considered a "node", and each node is connected to each other node with a single line, a total of seventy-eight lines are created. Within this cube, many other shapes can be found, including two-dimensionally flattened versions of the five platonic solids.
It is considered by some to be a symbol of sacred geometry, said to contain ancient, religious value depicting the fundamental forms of space and time. In this sense, it is a visual expression of the connections life weaves through all sentient beings.
Leonardo da Vinci studied the Flower of Life form and its mathematical properties. He drew the Flower of Life itself, as well as various components such as the Seed of Life. He drew geometric figures representing shapes such as the platonic solids, a sphere, a torus, etc., and also used the golden ratio of phi in his artwork; all of which may be derived from the Flower of Life design. 
The 13 circles that make up the framework for Metatron’s cube also have different interpretations and histories with different traditions.
Some traditions reference the 13 archangels of creation while others point to them representing the 13 energy centers and help bring balance to a particular Element or Elements and hence transcend dis-ease and co-create health, vitality and well-being. These thirteen elements are also referenced as the 13 sacred keys of the OmAhOm that hold the principles of evolution and the pathways to enlightenment.
The OmAhOm symbol is created by the 12 pointed Stellated Dodecahedron (through the 13th central point), is the vehicle that supports our conscious connection with the 13 Spheres of Metatron’s Cube and reinforces the connection of all things.
The interpretation of OmAhOm translates to:
I honour the Divine Love that exists within YOU
within ME and within ALL of CREATION
WE ARE ALL ONE
Transmutation circles in alchemy were believed to have the power to transform one element into another. There are many variations of the transmutation circles and what they were created for.
The Seal of Solomon
In alchemy, the combination of the fire and water symbols (up and down triangles) is known as the Seal of Solomon. The symbol is representative of the combination of opposites and transmutation. By combining the alchemical symbols for fire (upwards triangle) and water (downwards triangle), the alchemical symbols for earth and air are also created. The downwards facing triangle is divided along the center by the baseline of the opposite triangle. This is the alchemical symbol for earth. Conversely, the upwards triangle divided by the baseline of the downwards triangle is the alchemical symbol for air. The Seal of Solomon is all that is unified in perfect balance; the Spirit Wheel.
Squaring the circle was another major part of Renaissance alchemic ideas. It was believed that this symbol plus a man and a woman in the circle was all that was needed to create a philosopher's stone. 
Fullmetal Alchemists Transmutation Circle
Made popular by the anime Fullmetal Alchemist who borrows elements from sacred geometry and combines those with ancient symbols and texts from alchemist traditions they created their version of the transmutation circle. 
In that series lore, there are two rules that and alchemist must follow: transmuting gold and trying to bring someone back from the dead is not allowed.
NOTE: Neurohacker does not endorse trying to bring people back from the dead. It’s best to just focus your energy on being the best version of you.
