in following that train of thought, I'd say it depends on your perception of time.. Time as relative to the observer. This observer can choose to shift perspectives of time given their conscious awareness within the observing state, or naturally without fully realizing it has been done. This could be as simple as someone saying "it feels like just yesterday we were here" ~ while this same Timeframe to someone else Feels like it was long ago. Similar to the idea that an hour felt a lot longer when we were younger, the core of this seems to be our perception or Feeling of the passage of time. Now, if we look at those beautiful moments where time seems to stand still or even becomes completely irrelevant, there we fluently transcend 4th dimensional thought process and enhance spiritual clarity of our existence outside of time. Thus, linear reality can be seen for what is, a perception. A construct. And ultimately, a non-barrier to the limitless eternal being we know our selves to be.. :)
