Stanza: Barter not thy Selfhood for silver and gold

Barter not thy Selfhood for silver and gold; 
Sell not a burning flame for a spark half-cold; 
So says Firdowsi, the poet of vision and grace, 
Who brought to the East the dawn of brighter days: 
‘Be not a churl for filthy lucre’s sake, 
Count not thy coppers, whatever they may make.’
