====Essence-function in Korean Buddhism====
{{Main|Essence-Function}}

The polarity of absolute and relative is also expressed as "essence-function". The absolute is essence, the relative is function. They can't be seen as separate realities, but interpenetrate each other. The distinction does not "exclude any other frameworks such as ''neng-so'' or "subject-object" constructions", though the two "are completely different from each other in terms of their way of thinking".<ref>Park, Sung-bae  (1983).

In [[Korean Buddhism]], essence-function is also expressed as "body" and "the body's functions": {{quote|[A] more accurate definition (and the one the Korean populace is more familiar with) is "body" and "the body's functions". The implications of "essence/function" and "body/its functions" are similar, that is, both paradigms are used to point to a nondual relationship between the two concepts.<ref>Park, Sung-bae (2009).

A metaphor for essence-function is "A lamp and its light", a phrase from the ''[[Platform Sutra]]'', where "essence" is the lamp and "function" its light.<ref>Lai, Whalen (1979).
