廣弘明集 19.52

庖羲迺神。八象所以成列。周文克聖。六虛所以廣陳。蓋導俗之偏典。非通方之大訓。至如漢明自講局以儒術。簡文談疏復謝專經。猶靈若之觀井甃。雲夢之在胸中也。

When Paoxi was spirit-like, the eight trigrams were thereby set in array; when King Wen of Zhou attained sageliness, the six empty positions were thereby broadly displayed. These, however, are merely partial canons for guiding worldly matters, not the universal, great instructions. As for Emperor Ming of Han lecturing in person, he was restricted by Confucian arts; and when Emperor Jianwen expounded the commentaries, he fell short of the dedicated scriptures. It was like the Spirit of the River looking into the brickwork of a well, or Yunmeng Swamp merely held within one's breast.
