Wonhyo (617 – 686 CE) was one of the leading thinkers, writers and commentators of the Korean Buddhist tradition. Essence-Function (體用), a key concept in East Asian Buddhism and particularly that of Korean Buddhism, was refined in the syncretic philosophy and worldview of Wonhyo.
- Now, in the unhindered and unobstructed dharma-opening of the dharma-realm there is no dharma, and yet no non-dharma; no opening, and yet no non-opening. Thus it is neither large nor small, neither in a hurry nor taking its time; neither moving nor still, neither one nor many. Since it its not large, it can become an atom, leaving nothing behind. Since it is not small, it can contain all of space with room left over. Unhurried, it can include all the kalpas in the three time periods; not taking its time, it can enter fully into an instant.

- The mind of sentient beings as it is in itself has neither marks nor nature. It is like the ocean, like space. Since it is like space, there are no marks that are not subsumed within it. How could it contain a direction such as east or west? Since it is like the ocean, there is no nature that is preserved.
