俱舍論記 27.72

27.72

「傳說此四至無礙解故」者，此明加行。毘婆沙師有傳說：此四無礙解生如次。串習算計名、句、文身為法無礙解加行，串習佛語解諸法義為義無礙解加行，串習聲明論言詞為詞無礙解加行，串習因明論宗、因、喻等立破道理為辨無礙解加行。若於四處未得善巧，必不能生無礙解故。此非正義。

Regarding the passage from "Tradition says that these four" up to "for the analytical knowledges to arise": this clarifies preparatory cultivation (prayoga). The Vaibhāṣikas have a tradition saying: the arising of these four analytical knowledges occurs in this order. Habitual practice of calculating name-, phrase-, and phoneme-sets serves as the preparatory cultivation for Dharma-pratisaṃvid; habitual practice of the Buddha's word to understand the meanings of dharmas serves as the preparatory cultivation for Artha-pratisaṃvid; habitual practice of expressions in treatises on linguistics (śabdavidyā) serves as the preparatory cultivation for Nirukti-pratisaṃvid; habitual practice of establishing and refuting principles such as thesis, reason, and example in treatises on logic (hetuvidyā) serves as the preparatory cultivation for Pratibhāna-pratisaṃvid. If one has not attained skill in these four areas, the analytical knowledges will definitely not arise. This is not the orthodox position.
