觀無量壽佛經義疏 3.58

3.58

「『佛身高六十萬億那由他恒河沙由旬。』」佛身無量，機見有殊。文中所舉假以數量，顯非數量，欲彰佛身不可定故。即下文云「如前所說無量壽佛身量無邊，非是凡夫心力所及」，又云「或現大身滿虛空中」，舉此證前，知無限量。蠡盃酌海、丈尺量空，是可得乎？喻可見也。三、眉毫量。

" 'The Buddha's height is sixty trillion nayutas of Ganges sands of yojanas.'" The Buddha's body is immeasurable, and the capacities of beings see it differently. What is cited in the text uses numbers provisionally to show that it is beyond numbers, wishing to reveal that the Buddha's body cannot be fixed. As the text below says: "As explained before, the size of the Buddha Amitāyus' body is boundless, beyond the reach of the ordinary mortal's mental capacity"; and further says: "or manifesting a great body filling the empty sky." Citing these proves what precedes, knowing it has no limit or measure. Scooping the ocean with a snail-shell cup, measuring the sky with a yardstick—could that ever be achieved? The metaphor is apparent. Third, the size of the eyebrow-ūrṇā.
