“The Fine (or Wondrous) Dharma.”

The ultimate image is without form; the ultimate music is without sound. Being inaudible and subtle, and in the sphere beyond the reach of trace and speculation, how can [the Dharma] be expressed in terms of form? This is why the sūtras are variegated and doctrines are different. Yet, how can li [underlying the sūtras and doctrines] be of such nature? It is only because the fundamental ability (or subtle triggering-mechanism) (chi) and receptivity of ordinary people are not equal; there are a myriad of avenues of approach for prompting enlightenment. Hence, the Great Sage showed different styles of speech [for different groups of people] and manifested various teachings [for them].
