梵名烏瑟膩沙Uṣṇīṣa，佛頂上有一肉團，如髻狀，名肉髻，即三十二相中之無見頂相也。大般若三百八十一曰：「世尊頂上烏瑟膩沙，高顯周圓，猶如天蓋，是三十二。」玄應音義三曰：「肉髻，梵言嗢瑟尼沙，此云髻。即無上依經云：鬱瑟尼沙，頂骨涌起，自然成髻是也。」
烏失尼沙; 鬱失尼沙; 烏瑟尼沙; 鬱瑟尼沙; 烏瑟膩沙 uṣṇīṣa. One of the thirty-two marks (lakṣaṇa) of a Buddha; originally a conical or flame-shaped tuft of hair on the crown of a Buddha, in later ages represented as a fleshly excrescence on the skull itself; interpreted as coiffure of flesh. In China it is low and large at the base, sometimes with a tonsure on top of the protuberance.
古帝反梵言嗢瑟尼沙此云髻即無上依經云鬱尼沙頂骨涌起自然成髻是也經文從系作結非也嗢音烏沒反也
