1.263

釋名曰。服上曰衣。衣依也。所依以庇寒暑也。左傳曰。衣身之章也。白虎通曰。衣者隱也。所以隱形也。文子曰。衣足以蓋形。以禦風寒也。西天出家者衣。律有制度。應法而作。故曰法衣（西天一切帛未剪者皆呼為衣）。

The Shiming states: "Garments worn above are called yi (robes). Yi means yi (reliance); it is that upon which one relies to shelter from cold and heat." The Zuo zhuan states: "Robes are the emblems of the body." The Baihu tong states: "Robes (yi) mean concealing (yin); they are that by which the form is concealed." Wenzi states: "Robes are sufficient to cover the form and ward off wind and cold." Regarding the robes of those who renounce household life in the Western Heavens (India), the Vinaya contains regulations, and they must be made in accordance with the Dharma; hence they are called Dharma robes (in the Western Heavens, all uncut fabrics are referred to as robes).
