Second Law

Siddhartha is a wonderful book. As I was reading JLN's analogy, the image of Siddhartha as the boatman came to mind. Perhaps I saw the name, further down the page, perhaps it's synchronicity.
In the context of this discussion, I won't dare explore the concept of synchronicity further!
Time, in the sense of calendars and clocks, is usefully thought of in a linear manner. The only certainty in our universe is that entropy (disorder) always increases. This is the true measure of linear time. The more energy we expend in trying to impose order, the more we generate disorder in the dissipation of that energy.
The Second Law of Thermodynamics
However, I also see that we can never experience the progression of time. No matter how far or fast you run, you are always where (and when) you are.
