Thrice

This lesson you'd do well not to forget.
Your life could be the one its wisdom saves
At sea, when you're beleaguered and beset,
On every side by strife of wind and waves.
Despite the best of maps and bravest men,
For all their mighty names and massive forms,
There'll never be and there has never been
A ship or fleet secure against the storms.
When kings upon the main have clung to pride,
And held themselves as masters of the sea,
I've held them down beneath the crushing tide
Till they have learned that no one masters me.
But grace can still be found within the gales;
With fear and reverence, raise your ragged sail.
