Maritime
After you kick off from shore
swim into deep water
don your mask and snorkel
adjust it
if your mask fogs –
spit in it, rinse
adjust
then relax 
float
The in-air world is gone
the undersea waits
to share treasures 
some shout for your attention
others take time
focus
luck
If you listen carefully
if the water is clear
you might hear the sound of sand
tiny chimes twinking
the rhythm of ebb and flow
