俱舍論記 2.181

2.181

「論曰至形量差別」者，就長行中，一正釋頌本、二明根形狀、三明同分等。此即初文。鼻等三根至境方取，故根、境微相稱發識。此言等者，隨其所應根、境相觸名為量等，顯非能取過量境故。非無小分根能取少分境，若眼根傍布蒲桃上皮，若說眼根如丸如蒲桃內外。問：云何得見蒲桃內色？解云：皮薄故見。又解：縱使皮厚，天眼亦觀。《正理論》云「如見蒲桃、野棗果等。」耳根取境，隨其所應所發種種少大音聲，若聽蚊子聲，即根大境少；若聽雲聲，即根少境大。西方喚雷聲為雲聲，雷依雲起，從所依為名。若聽琴聲，即根、境量等。故《正理》第八云「耳根亦取蚊、雲、琴聲小、大、等量（已上論文）。」言聽蚊雲等者，等謂等量。又解：等取等量琴聲。前五色根極微成故，可得對境辨大、小、等。意無質礙，不可對境辨形量別，然容得說彼所緣境或大或小。餘文可知。

Regarding the passage from "The treatise says" up to "differences in shape and dimension": within the prose commentary, first it correctly explains the root verse, second it clarifies the shapes of the faculties, and third it clarifies similar-functioning [faculties] and the like. This is the first text. The three faculties such as the olfactory [faculty] apprehend only upon reaching the object; hence the atoms of the faculty and the object correspond to each other to generate consciousness. The word "equal" here means that according to what is appropriate, the touching of faculty and object is called equal in dimension, showing that they cannot apprehend an object that exceeds their dimension. It does not mean that a smaller portion of the faculty cannot apprehend a smaller portion of the object. If the visual faculty is spread out laterally upon the skin of a grape, or if it is said that the visual faculty is like a ball or the interior and exterior of a grape—Question: How can one see the color inside a grape? Explanation: It is seen because the skin is thin. Another explanation: Even if the skin were thick, the divine eye can also view it. The Nyāyānusāra says: "Just as seeing a grape, a wild jujube fruit, and the like." The auditory faculty apprehends objects according to what is appropriate, producing various small and large sounds: if listening to the sound of a mosquito, the faculty is large and the object is small; if listening to the sound of a cloud, the faculty is small and the object is large. In the Western regions, thunder is called "cloud sound"; thunder arises based on clouds, taking its name from its basis. If listening to the sound of a lute, the faculty and object are equal in dimension. Hence the Nyāyānusāra, fascicle 8, says: "The auditory faculty also apprehends the small, large, and equal dimensions of mosquito, cloud, and lute sounds (the above is the treatise text)." The statement "listening to mosquito, cloud, and the like": "the like" means equal dimension. Another explanation: "the like" includes the lute sound of equal dimension. Because the first five material faculties are composed of atoms, it is possible to distinguish large, small, and equal in relation to their objects. The mind (manas) lacks physical obstruction and cannot be distinguished in shape and dimension in relation to its objects, yet it is admissible to say that its cognitive objects are either large or small. The remaining text is understandable.
