"Serce jako nieme dudy nadyma pycha"
"The heart inflates pride like a silent bagpipe"; A variant of the proverbial commonplace [?; klisza przysłowiowa] "Nadętością pycha puchnie" [Pride swells with pomposity]; According to Kubik, who refers to »Nowa księga przysłów [polskich]« as his source (failing, however, to provide us with the basic bibliographical details), "the expression about inflating a silent bagpipe took its origin in the observation of the behaviour of the leather bag, slowly increasing in volume as a result of filling it with air by the musician before he began to play".
