（四十四）　司徒中郎張融作門律云。道之與佛逗極無二。吾見道士與道人戰儒墨。道人與道士辨是非。昔有鴻飛天。首積遠難亮。越人以為鳧。楚人以為乙。人自楚越鴻常一耳。以示汝南周顒。顒難之曰。虛無法性其寂雖同。位寂之方其旨則別。論所謂逗極無二。為逗極於虛無。為無二於法性耶。足下所宗本一物而為鴻乙耳。驅馳佛道無免二未。未知高鑒緣何識本。輕而宗之。其有旨乎（已上出南史）。

(44) Zhang Rong, Palace Gentleman of the Minister of Education, authored the *Menlü*, saying: "The Dao and the Buddha, reaching their ultimate, are not two. I see Daoists and Buddhist monks fighting over the Confucians and Mohists; I see Buddhist monks and Daoists debating right and wrong. Long ago, a wild goose flew across the sky; its distant form was hard to discern. A person of Yue took it to be a wild duck, while a person of Chu took it to be a swallow. The people were from Chu and Yue, but the wild goose was ever one and the same." He showed this to Zhou Yong of Runan. Yong challenged him, saying: "As for non-being and the Dharma-nature, though their tranquility is identical, the orientation of their positions of tranquility differs in principle. When the treatise states that 'reaching their ultimate they are not two,' does it mean reaching the ultimate in non-being, or being non-dual in the Dharma-nature? What you revere is fundamentally one single thing mistaken for a wild goose or a swallow. Rushing between Buddhism and Daoism, you cannot avoid the division of the two. I do not know by what cause your lofty vision recognized the root, enabling you to lightly revere it. Does it possess a deeper meaning?" (The above is from the *History of the Southern Dynasties*).
