12.9

evaṃ ca sati vedam adhītya snāyād iti smṛtir anugṛhītā bhavati/ atra hi vedādhyayanasamāvartanayor avyavadhānam avagamyate/ tāvake mate tv adhīte 'pi vede dharmavicārāya gurukule vastavyam/ tathā saty avyavadhānaṃ bādhyeta/ tasmād vicāraśāstrasya vaidhatvābhāvāt pāṭhamātreṇa svargasiddheḥ samāvartanaśāstrāc ca dharmavicāraśāstram anārambhaṇīyam iti pūrvapakṣasaṃkṣepaḥ/

Thus, too, we shall keep the Smṛti rule from being violated: "Having read the Veda, let him bathe." For this rule clearly implies that no long interval is to take place between reading the Veda and the student's return to his home; while, according to your opinion, after he had read the Veda, he would still have to remain in his preceptor's house to read the Mīmāṃsā discussions, and thus the idea of no interval between would be contradicted. Therefore for these three reasons, (a.) that the study of Mīmāṃsā is not enjoined, (b.) that heaven can be obtained by the simple reading of the text, and (c.) that the rule for the student's return to his home is thus fulfilled, we maintain that the study of the Mīmāṃsā discussions on duty is not to be commenced.
