The peacock and the fortress

In a desert, there was a fortress that prided itself on being the stronghold of the land. At night it dreamt of changing the world, but when it woke it found that it could not.
One day a peacock passed:
‘Pretty peacock’, said the fortress, ‘What prevents me changing the world?’
Nothing, said the peacock, Except the walls you have built around yourself.
‘But peacock!’, cried the fortress
‘At heart I am nothing but a well!’
Then I shall call you Jericho, replied the peacock
For what a castle you have constructed
Though you cannot move, and no-one visits
You have become invisible
No-one knows if a secret sorrow
Or a hidden treasure is buried here.
‘O Peacock!’, wept the fortress
The peacock opened her feathers, showing her true colours:
When has water tasted as sweet as this
Except when poured from a fountain called Love?
And immediately the words appeared on the fortress’ walls:
Unlimited, except by myselves.
