鄔波尸殺曇分（上烏古反梵語數法之名言其極也亦如花嚴經中阿僧祇品云不可說不可說轉之類是也舊解云鄔波云少尸殺曇云近分言是隣虛之塵將比其一未）。

鄔波尸殺曇分 (upaśiṣṭāṃśa: the upper character has the fanqie wu + gu. It is a Sanskrit term for a number, designating the ultimate [infinitesimal fraction], comparable to phrases like 'the turn of the ineffable and ineffable' in the Asamkhyeya Chapter of the Avataṃsaka-sūtra. The older explanation says: 'upa' means a tiny amount, 'śiṣṭa' means approaching, and 'aṃśa' means a fraction; it is said to compare even a single atom of the finest dust to it, yet it falls short).
