Death and Time

Ticking clocks are the best for this.

Think of it first as it is.  A tic, each representing one second, 60 of which ate in a minute, 60 of which are in an hour, etc counting down to your own demise.

Then think of it completely differently.  Think of it not as a progression down a finite linear scale, but rather just a rhythm.  A cyclic occurrence, manifesting the momentum of being while maintaining it, just

some calming noise occurring sequentially in that corner.

It's one thing to read it but if I've described it correctly is rather incredible to experience.  I believe I can eventually take this to digital clocks and to more and more of my daily existence, and that ones perspective on time can be both the cause and effect of ones perspective on death.
