Master Dahui Zonggao said, “There is nothing so special for a Chan practitioner to talk about koans such as ‘dry shit stick’, ‘sawing the sliding weight of steelyard’, ‘three pounds of hemp’, or ‘a dog’s Buddha nature’. It is not enough to merely do the talking; you’ve got to have true realization. And once you are truly realized, if your teacher deliberately denies it, he will bear the karma.”
Chan practitioners must remember this and stop paying lip service to Samadhi. Only true realization counts.
by Grand Master Lian Chi (蓮池大師), the Eighth Patriarch of Pure Land Buddhism
實悟 – 錄自明末蓮池大師《竹窗隨筆》(初筆)
妙喜云:「若是乾屎橛如是說得落時，如鋸解稱鎚、麻三斤、狗子佛性等，皆可如是說得。既不可如是說，須是悟始得。你若實得悟，師家故言不是，亦招因果不小。」學者當初記妙喜此語，息卻口頭三昧而求實悟。
