Pu is a Chinese term that translates to 'uncarved block' or 'raw material,' representing the natural state of simplicity and potentiality in Taoism. It symbolizes the idea of returning to a state of untainted simplicity, where things are in their most authentic form, untouched by societal influences or complexities. This concept encourages individuals to embrace their true nature and live in harmony with the Tao, aligning with the broader philosophical themes of balance and spontaneity in Taoist thought.
