“Time present and time past
Are both perhaps present in time future,
And time future contained in time past.
If all time is eternally present
All time is unredeemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.
Footfalls echo in the memory
Down the passage which we did not take
Towards the door we never opened
Into the rose-garden. My words echo
Thus, in your mind.”

T.S. Eliot, Four Quarters – Burnt Norton

This extract is the start of the Four Quarters poem. It is always in my mind as I sit on the shore watching the waves rolling back and forth. Time and tide in continuous movement, creating and erasing its path. These images represent the delicate nature of each moment vanishing before your eyes.
