It is a white duck
During the rains a band of ducks afloat
against the cloud laden skies
only remind of the duck
The duck that wings unseen in the morning
and in the night
carrying the sunbeams and moonbeams
in its roseate beaks
The duck that lives on light
The duck that is the mount of Knowledge and Wisdom
Knowledge and wisdom always fights with one another
But when they ride the duck
they hold each other with loving arms
Or else they might fall from the shoulders of the duck
and break into pieces
In that case no one will be able to bring the pieces together
Alas! Alas!
