There is what is within. And then there is all that is without. However, in essence, the without is but a collection of other withins. So if I stepped out of myself, I would observe that what is within other people is proportionate to that which is within myself. Without–in all of this collection of withins–is an extroverted form of myself. Or an introverted form of the cosmos.
But to directly and immediately equate the two together would be a fallacy, because while at some ultimate level everything within and without harmonizes like a yolk harmonizes within an egg, they are not one and the same at any given moment in time. It is only when seen from a steadfast, timeless, eternal viewpoint that they pan out into one. If you flash framed the Now right now, then you would notice more the contrasts, the differences, the distinctiveness of all people from one another from different peoples in different times. The yolk would seem to be distinguished from the egg just as when you cut in half a hardboiled egg. You could pop it out as if it were a separate piece altogether.
As if the children were distinct from the adults, who are distinct from the old. As if the college students were distinct from the young professionals, as if distinct from high school students. As if the sun were distinct from the moon, and this solar system distinct from the milky way.
As if my thoughts and my feelings were distinct from your fingers. As if your eyes were distinct from the concrete, from the summer air, as if the currents carrying a Florida thunderstorm were distinct from the waves cutting at the Taiwanese shore. As if this breath, this moment, this pinnacle of your rushing heart was distinct from the world.
