Symmetry arises from an underlying pattern of reflection.There are a variety of patterns in the world, that point to the underlying nature of reality. Three primary patterns include 'Many from One', Reflection, and the Hollow. Let's explore these and see how they connect and hint at the unseen reality behind them.
 
We can see 'Many from One' almost everywhere we look. The human body, with its central torso, arms, legs, fingers and toes, shows many from one. A tree branching out shows it. Fork lightning shows it. Rivers and streams from the sea show it. The propagation of animals and plants show it: seeds are scattered and multiply. The evolution of species shows it.
 
We physically see Reflection wherever we look, as that's the way the eye works, inverting light that passes through the lens of the eye. What we see is also a reflection of light off surfaces. We can see our reflection when light rebounds from the face onto a smooth reflective surface. Sounds also rebound and reflect off surfaces. The symmetry of the human body is a form of reflection, where the left side is to some degree a reflection of the right side. This symmetry arises from an underlying pattern of reflection. Reflection underlies the appearance of opposites in the world, where we could say that high is a reflection of low, far is a reflection of near, and so on. Furthermore, Reflection and opposites give rise to fluctuation and vibration.
 
The Hollow is perhaps less obvious. The bones in the body are hollow. The lungs are hollow, as well as reflective, breathing in and breathing out. The throat and mouth cavity are hollow and allow the projection of sound as the voice. The stems of plants are hollow. Bubbles are hollow. Caves within the earth are hollowed out holes. Whirlpools, cyclones, and hurricanes are known for their spinning force around a hollow centre.
 
These patterns are all expressed in the natural world and in the human-made world. For example, in music making we have hollow instruments like the flute, the trombone and the drum, and we have instruments that use the fluctuation of strings (stemming from reflection), such as the violin and the piano. When we listen to a recorded piece of music we can pick out the many instruments sounding within it. Delay and reverb effects are used, giving reflective qualities to the sounds. One recording is made and distributed as many across the world. Actually, the delay effect used in music making demonstrates both the Reflection and 'Many from One' pattern, when it is used to imitate a distant echo, with the sound bouncing off 'surfaces' and seeming to multiply.
 
What do these patterns tell us about the underlying reality of the universe? They reflect the Oneness that is the core nature of reality. The Hollow hints at the Full-Emptiness of reality, where the total sum of all opposites equals zero. The hollow central cavity seems empty but is actually full, whether full of air or water etc. It points to the Singularity that was before the universe appeared, which contained all in an unmanifest unity, when everything was nothing. 'Many from One' is how the universe came to appear as it does now. The One seemed to divide itself into itself and its opposite (Reflection) and this bifurcation multiplied in the 'Many from One' pattern, creating a world of reflection and fluctuating frequencies. Note that 'Many from One' is itself a reflection, where the One reflects itself into its opposite, many. Or so it seems.
 
The crucial understanding is that although there seems to be many coming from one, they never really leave the Oneness. The Singularity that contained all in unmanifest harmony (Full-Emptiness) is still present throughout the appearance and disappearance of the world of opposites. The appearance of what is and what isn't (its reflection) is only a seeming separation of the Singularity, which remains timelessly full and empty. There is only ever What Is. Its reflection doesn't really exist, but reflection is the play of opposites which allows the Singularity to look back at itself, within itself. Reflection makes the world appear within itself.
 
Although space and time seems to divide the Singularity into many, rising out of the Full-Emptiness, the completion of space and time is its returning to unmanifest Oneness. All the while the Oneness remains as it is, seemingly at the heart of the universe, as the Hollow Hole, or rather the Hollow Whole.
 
Let's try to explain that a simpler way. What we call space and time is the seeming division of the primordial Singularity. Full-Emptiness seems to have divided into what it is and what it is not, its reflective opposite. Oneness seems to have divided into many, by aid of reflection. Yet the totality remains the same. The universe, or What Is, is timelessly always what it is. It seems that the Hollow, the Full-Emptiness, remains at the Heart of space and time, but it is the totality of space and time. The Singularity remains timelessly as it is.
