peacock eats poison,
transforms it into beauty—
thus I heard it said...

Once upon a time a group of people discovered a poisonous plant growing nearby. Fear rose in their hearts and they immediately wanted to uproot it and destroy it.
Another group came through and saw the poisonous plant and wanted to protect the people and the plant from harm by putting a fence around it. 
Yet a third group came across this poisonous plant and were pleased, because they recognized that the poison could be transformed into powerful medicine. 
Finally a peacock entered the garden and, on the spot, gobbled up the plant. The poison consumed was the source of its brilliant and beautiful plumage.
