僧伽胝（音知舊曰僧伽梨此云複衣即今僧之大衣是也下從九條上至二十五條但取奇數九種差別具如律文所說佛制入王宮時入聚落時摧伏外道時見猛獸時應着此衣）。

僧伽胝 (pronounced *zhī*; formerly called 僧伽梨; this translates as 'composite robe' (saṅghāṭī), which is precisely the great robe of contemporary monks; ranging from nine strips at the lowest to twenty-five strips at the highest, it takes only odd numbers, having nine varieties of distinction, fully explained in the Vinaya texts. The Buddha instituted that when entering royal palaces, entering villages, subduing non-Buddhists, or encountering ferocious beasts, one should wear this robe).
