第三段中，「如彼嬰兒於非金中而生金想」舉化所隨，偏舉其喻。「如來亦爾，於不淨中而說為淨」舉佛化相偏舉其法，「以得第一則無虛妄」明佛不虛。

In the third section, "Just as that infant forms the notion of gold with respect to what is not gold" brings up that which the transformation accommodates, uniquely citing the simile. "The Tathāgata is also like this; with respect to what is impure, he speaks of it as pure" brings up the characteristics of the Buddha's transformation, uniquely citing the dharma. "Because he has attained the ultimate, he is free from falsehood" clarifies that the Buddha is not deceptive.
