Only about eight minutes of your time is likely powerfully illuminating as a result of then understanding the content of the embedded video herein.
My two cents? Since I am (at least typically) in a giving mood, let us humbly make it three cents (more, if possible) in this metaphorical sense.
When we look within reality, we simply see relativity.
To clarify, mainstream physics (e.g. mass/energy equivalency, quantum field theory, string theory) only tells us that reality is pure energy, so seamless currents of energy without any objective boundary.
The boundaries drawn within your mind (e.g. the ones that define words, objects, people, and any other outcome that I may be missing) are simply modulations of energy. Your brain is mass, and mass is highly condensed energy. Your neurological symphony is energy.
The pure wave of energy forms the illusion of any objective boundary.
That illusion is something defined relative to that outside of that definition.
No matter how we tell our stories (the expression of illusionary boundaries), the only true constant is the perfectly stabilized energy of reality, which is objectively synonymous with you (and anyone/anything else) due to the nonexistence of any objective boundary.
