Spiro ergo prospero
Life arises from deep within:

The sacrum resembles a rearing cobra with a flared hood. This “holy bone” is located between the wings of the pelvis. In Egypt, the snake conveyed royalty, immortality and divinity and was called the Uraeus. As a medical symbol, cobras represented life itself—the magical umbilical cord uniting the mundane with the mystical.

The holes in the sacrum are called the sacral foramina. They provide an opening for the sacral nerves and blood vessels to pass through the bone. In other words, a bit like the number eight expressed within an inverted triangle. Combined, they signify the “life force” of the universe that the ancient Egyptians venerated in the Ankh.

In geometry, a simplex is so-named because it represents the simplest possible polytope made from line segments in any given dimension. This is the “V” behind the concept of the Holy Trinity—the fundamental shape that inspires our world. The triangle then, is like the tip of Excalibur thrusting into the stone.
Truth hints at nonduality—the belief that there is just one eternal Source in existence and that everything in the fractal universe is an inseparable part of it. In mathematics, “fractal” is a term used to describe geometric shapes containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. This is the universal Self-similar kernel that looks like a rearing serpent:

What colour is the universe? Well, infrared is “invisible light” that makes up most of the energy hitting Earth’s surface. This electromagnetic radiation has a longer wavelength than visible light and therefore doesn’t activate the photoreceptors in our eyes. If infra means “below,” we might say that the feminine and masculine snakes are the energy and momentum aspects of the cosmic infrared background made up of waves and particles.

As creation is sounded, the Sri Yantra pattern appears. This “Yantra of Creation” blossoms as the first sound is intoned. The word yantra means “geometric mantra” and is sometimes known as a power diagram. At the centre is the bindu or “dot” which in maths is the alpha or “unit” that makes up figurate numbers. The Egyptians drew 0D like this:

If we imagine the spinal cord as a straight line, then we can take the 19 vertebra of the 1D cervical and thoracic spine and arrange them in 2D. In other words, we can start to play around with multidimensional shapes that have the same amount of units. Here we are reminded of the holy bone that can be expressed like this:

Going a step further, the 2D centred triangle of 19 balls above (the sacrum) can be rearranged into a 3D octahedron below (the heart):

And the tesseract (the soul). This is a 4D analogue of a cube—the hypercube is to the cube as the cube is to the square. In geometry, the rectified tesseract is bounded by 24 cells, 8 cuboctahedra and 16 tetrahedra. This uniform 4-polytope can be constructed from the tesseract by truncating its vertices at the midpoints of its edges.

This is the Soul Star which can be seen above as an orthographic projection. This “seat of the soul” is the catalyst for deepening our relationship with the universe. Once this Kabbalistic Tree of Life starts to grow, we experience more coherence. The quartz net above then, also implies the rhombicuboctahedron:

Above: when is a hexagram an octagram?
This eighth chakra is the gateway between our immortal soul and our mortal personality. Activating the star within this shape gives us heightened spiritual awareness and divine compassion. The higher self is deemed to be the best version of ourselves, so when we embody it we can reassess our decisions with more spiritual depth.
So the 19 balls can be reorganised interdimensionally. This is how the lower, middle and higher realms reflect our subconscious, conscious and superconscious minds (instinct as emotion as thought). More profoundly, the mathematical proof of the Sri Yantra also implies the Soul Star.

Above: universal awareness
Inside a person, the”master switch” of consciousness is at the base of the spine. Kundalini translates from Sanskrit as “coiled snake” and describes the dormant energy that lies curled in the belly. When this powerful force is activated, we become aware of our divine nature and our connection to the universe. We understand that consciousness is omnipresent as we expand beyond our physical limits.

Diaphragmatic breathing in humans encourages a full gas exchange—the beneficial trade of incoming oxygen for outgoing carbon dioxide. Not surprisingly, this belly breathing slows the heartbeat and lowers blood pressure. This process also activates the vagus nerve, which is part of the parasympathetic nervous system. This leads to less mental chatter and more relaxed states.
So by arousing our creative essence with tantric breathing we are giving birth to a dot, a line, a triangle, an octahedron and a rectified tesseract. Where should we focus our attention? Well, the thymus (Vyapini) is located between the throat (Vishuddha) and the heart (Anahata). Spiritually, this eighth chakra gives rise to the High Heart of joy, bliss and unconditional love that can only be experienced by the death of the ego:

In 5D geometry, a truncated 5-simplex is a convex uniform 5-polytope, being a truncation of the regular 5-simplex. The vertices of the bitruncated 5-simplex can be most simply constructed on a hyperplane in 6-space. But this is academic—when we experience 5D, we literally ARE unconditional love. This higher form of consciousness is just pure bliss, so we don’t need to “do” and we don’t need to “have”. The divine rapture!
I breathe therefore I prosper.
