Question: Why explain the ten suchnesses only in terms of the two dharma realms of hell and buddha? Answer: Hell is the most evil, and the realm of buddhas is the most good; now, explaining the ten suchnesses in terms of good and evil makes them visible, so that the ten suchnesses of the intermediate eight realms can be known by analogy without needing detailed explanation. For one who grasps the idea, this is also sufficient to dispel doubt; for one who does not grasp the idea, further prolixity would be useless. If explaining the ten realms and hundred suchnesses distinctly, their distinctions are as presented before. Now, discussing from the perspective of the perfect [teaching], the mind in a single thought-moment is endowed with the hundred realms and thousand suchnesses; therefore this mind is designated as the inconceivable object.
