‘据《虚云法师年谱》记载,虚云法师初到云门寺时,只见荆棘丛中残存古寺,内肉身一尊,为云门开宗道场。此云门祖师肉身像为虚云法师于云门寺时所摄,后肉身被毁,仅存此照片收录于50年代出版之《虚云法师年谱》中。’
‘According to the Biography of the Dharma-Master Xu Yun – when he arrived at the ancient Yun-Men Temple, it was in ruins and covered in a thick overgrowth of plants and bushes, etc. The only part that was still intact (and oddly preserved) was the central meditation hall which contained the mummified body of Master Yun-Men Wen-Yan (雲門文偃) [864-949]. Master Yun-Men was still sat upright in the meditation position and it seemed that the power of his spiritual insight was keeping the building from collapsing. At this time, Master Xu Yun arranged for the body of Master Yun-Men to be photographed – and requested that this picture be included as part of his biography. Later, when this mummified body went missing – this photograph remains the only evidence that the body of Master Yun-Men ever existed.’
