The world around you is not everything all at one moment and in the same place.

It is separated out into compartmentalized steps :

Understand what step you are on
Chose you next one you will take,

Look up at where you are going -
But don’t forget to watch your feet at each
next
     Step.

The things that are here, are here now
And you are here now

All the thing that have been, or may come to pass,

They cast shadows from themselves that we can watch dancing at the back of the cave.

But we are Now.
And Now needs to be dealt with now.
