烏瑟膩沙（梵語也如來頂相之號也觀佛三昧海經云如來頂上肉髻團圓當中涌起高顯端嚴猶如天葢又一譯云無見頂相各有深義也）。

烏瑟膩沙 [uṣṇīṣa] (Sanskrit; the designation of the Tathāgata's cranial protuberance. The Guan fo sanmei hai jing says: the fleshy protuberance atop the Tathāgata's crown is round, surging up in the center, elevated and magnificent, resembling a heavenly canopy. Another translation renders it 'the invisible cranial protuberance'; each carries a profound meaning).
