Time, as we know it, is an illusion. There is only the NOW – the Present moment.
We think of time as having three parts – Past, Present, Future. But the Past is only a collection of memories. We can’t experience the Past, we can only remember it. And we can only remember it in the Present.
And the Future is only a mental construct in the Present. We can’t experience the Future until it “becomes” the Present.
That leaves us only with the Present – the ever-changing Present. It’s always NOW. But it’s an ever changing NOW. In an effort to cope with the change, we came up with the concept of time.
