【八廓部位歌】
瞳孔属于水廓，黑睛属于风廓；天廓的部位与白睛相同。内眦（大眼角）属于火廓和雷廓，外眦（小眼角）属于山廓和泽廓；上下眼睑属于地廓和宫（此处指代眼轮匝肌或眼睑整体结构，结合上下文“两胞属坤”）。
【注释】
所谓八廓，是指水廓、风廓、天廓、火廓、雷廓、山廓、泽廓、地廓。称为“廓”，就像城郭保卫御守的含义一样。瞳孔，归属于坎卦对应的水廓。黑睛，归属于巽卦对应的风廓。白睛，归属于乾卦对应的天廓。内眦较大，归属于离卦的火廓和震卦的雷廓。外眦较小，归属于艮卦的山廓和兑卦的泽廓。上下眼睑归属于坤卦的地廓。这是为了阐明八廓依据八卦来命名，以此指示六腑、命门和心包络在眼部的对应部位。

【八廓所属歌】
津液水廓归属于膀胱，养化风廓是胆的方位，传导天廓归属于大肠，水谷地廓是胃的家乡，关泉雷廓由命门主宰，抱阳内眦之火归属于小肠，外眦三焦为清净泽廓，会阴山廓属于心包络的疆域。
【注释】
内眦之火廓，指的是内眦火廓，归属于小肠。外眦三焦清净泽廓，指的是外眦归属于三焦，即清净泽廓。津液廓就是水廓，水廓归属于肾（注：原文此处逻辑有争议，通常水廓属膀胱/肾，但后文解释强调膀胱为府），肾与膀胱互为表里，膀胱是津液汇聚之府，所以又被称为津液廓。养化廓就是风廓，风廓归属于肝，肝与胆互为表里，胆为少阳经，主生长化育，所以又被称为养化廓。传导廓就是天廓，天廓归属于肺，肺与大肠互为表里，大肠是传导之官，所以又被称为传导廓。水谷廓就是地廓，地廓归属于脾，脾与胃互为表里，胃受纳水谷，所以又被称为水谷廓。抱阳廓就是火廓，火廓归属于心，心与小肠互为表里，因为附属于阳，所以又被称为抱阳廓。关泉廓就是雷廓，命门是龙雷之火，所以名为关泉，它依附于火廓。清净廓就是泽廓，三焦是阳相火，蒸腾气化水谷，是决渎之官，所以名为清净，它依附于火廓。会阴廓就是山廓，心包络是阴相火，根据附属于心作为臣使之官，所以名为会阴，它依附于火廓。
The pupil corresponds to the Water Palisade (Shui Kuo), and the cornea corresponds to the Wind Palisade (Feng Kuo); the Heaven Palisade (Tian Kuo) shares the same location as the sclera. The inner canthus belongs to the Fire (Huo) and Thunder (Lei) Palisades, while the outer canthus belongs to the Mountain (Shan) and Lake (Ze) Palisades; the upper and lower eyelids belong to the Earth Palisade (Di Kuo).

The Fluids Palisade is the Water Palisade; the Water Palisade belongs to the Kidney (Zhuo: Note: Text earlier states Water Palisade belongs to Bladder; here note links it to Kidney due to interior-exterior relationship).
