An Instance is an occurrence or a happening.
It is something that occurs to me or happens to me.
A normal instance upholds reality as normal and unchanging.
An abnormal instance is seen as surreal or paranormal or is an experience that is seen as an accident or a disaster that changes current reality.
I see a disastrous instance as changing my normal reality against my wishes.
Instances of change are seen as blips in the One Reality of Life and are perceived as changes to reality over time.
An Instant is a point in space and time.
We perceive points in space as places and points in time as moments, which we see as different aspects of reality.
When I observe a particular point in space & time, I see an Instant of Reality.
An instant of reality is the product of that point in space and that point in time.
Space-Time creates Instants of Reality
Without space-time their is no point to reality.
An Instant is continuously changing.
That is the point of Reality and the point of Life.
When I observe the instant, I get the point.
An instance happens to me, whereas an instant is of my own creation.
