跏趺（上音加下音夫二字皆相承俗用也正作加跗二形鄭注儀禮云跗足上也顧野王云足面上也案金剛頂瑜伽儀云坐有二種謂全加半加結加坐即全加也加跗坐即半加也謂降魔吉祥等也如前已釋也）。

跏趺 (for the first character, pronounced 加 [jiā]; for the second character, pronounced 夫 [fū]. Both characters are conventionally used in common practice; standardly they are written as the two forms 加跗. Zheng's commentary on the Yili says: “跗 is the upper side of the foot.” Gu Yewang says: “The top of the foot.” It is noted that the Jingangding yuqie yi says: “There are two kinds of seated postures, namely full cross-legged (全加) and half cross-legged (半加). To sit crossing both legs is full cross-legged; to sit with foot atop thigh is half cross-legged. These refer to postures for subduing Māra, auspiciousness, and so forth, as explained previously.”)
