The present is eternal. Divisions of time exist only in abstraction; the past and the future are creations of the mind and do not exist independent of experience.

Time comes from the PIE root di-mon-. Di, from da, meaning to divide, or cut up.^[source] This concept of chopping up serves as a metaphor for the experience of change, the experience of passing through time. Time does not pass, we pass through it. In the words of De Broglie...

In space-time, everything which for each of us constitutes the past, the present, and the future is given en bloc . . . Each observer, as his time passes, discovers, so to speak, new slices of space-time which appear to him as successive aspects of the material world, though in reality the ensemble of events constituting space-time exist prior to his knowledge of them.

(Capra 1975, 172)

We like to divide time up into three groups. Past, Present, and Future. But where are the boundaries between these? Does "now" last for one second? A nanosecond? If you cannot say how long 'now' lasts, then you cannot say where the past and future begin. Thus the illusory nature are revealed by this. They are nothing but constructs of the mind, of the intellect.

All that exists is the eternal now.
