Places in the Ground

There are places in the ground
Where treasure chests can still be found
But all the wisdom buried there
Has long decayed from lack of wear

How do I know that once there lied
A secret treasure in disguise?
I read a book.
I criticize.

But suddenly I turn a page
And hear the wisdom of a sage
Then trample to some piece of land
And find a headstone in the sand
And know that treasure did abound

There are places in the ground
