श्रवणाध्ययनार्थप्रतिषेधात् स्मृतेश्च ॥ ३८ ॥
śravaṇādhyayanārthapratiṣedhāt smṛteśca || 38 ||
śravaṇa-adhyayana-artha-pratiṣedhāt—Because of the prohibition of hearing, studying, and understanding; smṛteḥ—in the Smriti; ca—and.
38. And because of the prohibition in the Smriti of hearing and studying (the Vedas) and knowing their meaning and performing Vedic rites (to Sudras, they are not entitled to the knowledge of Brahman).
Sutras 34-38 disqualify the Sudra for the knowledge of Brahman through the study of the Vedas. But it is possible for them to attain that knowledge through the Puranas and the epics (Ramayana and Mahabharata).
The digression begun from Sutra 26 ends here and the general topic is again taken up.
