உச்சிஷ்ட நிலையில் அவசரமாகச் சென்று சுவாத்யாயத்தில் ஈடுபடுபவனும், மோகத்தால் அனத்தியாய காலத்திலும் படிக்கும் த்விஜனும்—

Educational Q&A
Vedic study (svādhyāya) must be done with proper purity and at permitted times; studying with an impure mouth (ucchiṣṭa) or during an anadhyāya period is portrayed as a serious breach that destroys longevity and the fruit of learning.
Bhishma instructs by citing an old traditional account attributed to Yama: Yama warns that those who recite/study the Veda in impure or prohibited conditions incur grave consequences, so the wise should avoid svādhyāya at forbidden times.
