Can you read what you cannot see?

Tossed and turned awaiting to learn
The things that can never be written down
Where to find the piece of pie
Of a taste that can never be found

So simple it is to look about
Until your eyes are closed to see
Listen to the sound when no one is around
Understand the words they speak

Find what is lost under a rock
Without kicking it with your feet
Drink the water from a well that cannot be found
And always keep your thirst

Satisfy your hunger with what you sink your teeth into
But be careful when you open your mouth
A sense of smell to know when trouble is about
Then it is time to turn around
