四分律行事鈔資持記 3.135

3.135

皮革中，初科為三，初制不畜。狙，都達反；《山海經》云：獸形如狼。又不下，制不坐。除寶床者，縱在俗舍，亦不得故。不得乞下，明乞用開制。戶樞即今之門臼。帳軒，舊云：即車上之屋，一頭低，一頭舉故。（或似今時床帳軒屋。）律因六群作帳軒如王臣，俗呵而制。《三千》中。善助者，用修禪故。熟韋即已熏皮。指餘法者，彼有五相，一廣一尺，二長八尺，三頭有鉤，四當三重，五不得用金鉤；從後轉向前句兩膝過，束令不動。此非常用，故令屏著。寒雪國開襪，即此方所宜。

In [the section on] leather, the first heading has three parts: first, prohibiting keeping it. *Ju* is pronounced with the fanqie *du* and *da*; the *Classic of Mountains and Seas* says it is an animal shaped like a wolf. 'Moreover, not...' and below prohibits sitting on it; 'except for jeweled couches' means that even in secular households it is not permitted. 'One must not beg...' and below explains the exceptions and prohibitions regarding begging for and using it. 'Door pivot' is what is nowadays called a door socket. 'Curtained carriage canopy' was anciently explained as a roof on a carriage, low at one end and raised at the other (or like modern bed-curtain frames). In the Vinaya, because the group of six made carriage canopies like kings and ministers and the laity criticized them, it was prohibited. In the *Three Thousand [Rules]*, 'skilful support' is used for cultivating meditation. 'Tanned leather' is leather that has been smoked. 'Pointing to the remaining methods' refers to its five features: first, one foot wide; second, eight feet long; third, hooks at the ends; fourth, three layers; fifth, not using gold hooks. It is passed from behind to the front to hook around both knees, binding them securely so they do not move. Since this is not for everyday use, it must be worn in a secluded place. In cold, snowy lands socks are permitted, which is suited to this region.
