Squeeze your feet into synthetic fins.
See the world in big rubbery lenses.
Don’t forget the snorkel, of course! Bite tight.
Hobble to the shore,
Where the two worlds meet.

The sea splashes gently on the sand.
It hurls itself forward
And then recedes back.
Its motions are like gestures,
Telling you to draw close
And closer.
Its peaceful surface is an invitation itself,
Painted blue and glittered with sunshine.

Accept the invitation with gladness.
Don't be afraid!
Let the briny waters embrace you.
Let the cold tickle your skin.
Let the waves rock you back and forth.

You have entered a grand ballroom
Illuminated with a majestic chandelier of refracting sunlight.
The colorful corals with shapes of mounds, disks, and crowns,
Sway with the rhythm of the current.
The fishes dance around and about,
Each beaded with scales of various vibrant colors.

And then the reef ends.

The colors abruptly plunge into a black abyss.  
Look down and allow yourself to be
Filled with fear, terror,
Or maybe
Insatiable curiosity.
Now let that curiosity stir discontentment in you:
Discontentment with snorkeling.
Let it ignite a craving for
More thrill, more wonder.

It's time to go deep sea diving.
