Kazan Sōki (華山宗杞) (1663–1731) was a Rinzai #Zen master known for his extreme asceticism & solitary practice in the mountains. Rejecting worldly comforts, he sought to test the limits of #mind & #body by #meditating in freezing conditions, often living in caves & exposing his #NakedBody to harsh elements. He rarely wore clothes, sometimes donning only a fundoshi (loincloth), believing that direct contact with #nature deepened his understanding of #Zen & the #impermanence of existence. (1/3)
