Kāśyapa! Suppose the various trees and grasses of the one thousand million Sumeru-worlds

Delusion arises when one deviates from li; delusions vary in a myriad of ways. By turning one’s back [to delusion] one becomes enlightened to li. li must be nondual; the Tao of the Thus Come One is one. Beings go against (the One), calling it three. The three originated in beings’ own disposition, but li has remained one always. It is like the fact that, though the clouds and rains fall equally [on all the medicinal trees], the medicinal trees themselves vary in a myriad of ways. It is the medicinal trees that are varied in a myriad of ways, not the clouds and rains. What he said in parable of the difference and similarity was meant to show how [the three] turn out to be unified. Kāśyapa comprehended this purport, achieving the ultimate “rarely” experienced by any. [The words] three thousand refer to the single domain of the Buddha’s transformative teaching in its entirety.
