Like the smile of Sakyamuni as he grasped the flower and the idea embodied in the saying of Hui Neng, Chan's Sixth Patriarch, that "originally there was nothing, from where is dirt stirred up?" the ultimate aim of Chan is to "clear your heart to realize your essential nature; to realize your nature and become a Buddha."
如釋迦牟尼的拈花微笑、六祖慧能的「本來無一物，何處惹塵埃」，終極目的都是「明心見性，見性成佛」。
