俱舍論疏 5.239

5.239

論「豈不此字至亦書分名」，此問答分別也。豈不此字即是紙上屈曲色名為字？問也。答云：非為顯書分色字，製造諸不相應字；但為顯不相應字，製造色書字。依此色字記持不相應字，及將色字傳流異方及於後代，是故不相應諸字非同書字。

The Śāstra states: "Are not these letters... also called parts of writing?" This is an analysis through question and answer. Are not these letters precisely the curved material shapes on paper called characters? This is the question. The answer states: it is not to reveal the material letters of writing that the unassociated phonemes were created; rather, it is to reveal the unassociated phonemes that material written characters were created. Relying on these material characters, one remembers and retains the unassociated phonemes and transmits the material characters to other lands and to future generations; therefore, the unassociated phonemes are not identical to written characters.
