外論曰。老教容止威儀拜伏揖讓玄巾黃褐持笏曳履法象表明。蓋華夏之古制（彈曰。道士元來本著儒服不異俗人。至周武世始有橫被。二十四縫以應陰陽二十四氣也。出自人情亦無典據也）釋訓袈裟左袨偏袒右肩。全幅橫縵之裙。半片倚支之服。禿髮露頂狗踞狐蹲。非預人倫寔戎狄之風也。豈用茲形制匹我威儀。此容服之異九也。

The External Treatise states: In the teaching of Laozi, deportment, prostrations, bowings, yielding, dark caps, yellow coarse garments, holding tablets, and trailing shoes manifest the principles in outward forms. These are indeed the ancient regulations of China. (A refutation notes: Daoist masters originally wore Ruist attire, no different from commoners. Only in the reign of Emperor Wu of the Northern Zhou did they begin wearing crosswise mantles with twenty-four seams to correspond to the twenty-four qi of yin and yang. This arose from human contrivance and lacks any canonical basis.) The Śākya instructions prescribe the kāṣāya, with the collar to the left and baring the right shoulder; a skirt made of an entire bolt of plain cloth; and a garment draped over one shoulder. With shaved hair, exposed crowns, sitting like dogs, and crouching like foxes, they do not participate in human relations, which is truly the custom of the barbarian tribes. How could such forms and attire compare with our decorum? This is the ninth [difference], the difference in deportment and attire.
