अन्वयः

जुगुप्सितः despicable person, यः who, ज्येष्ठस्य of elder's, भ्रातुः brother's, जीवतः while he was alive, धर्मेण from the point of view of morality, मातरं motherlike, भार्याम् wife, प्रियाम् loved, महिषीम् queen, स्वीकरोति he took over (used her as his wife), महात्मना by the great, भ्रात्रा by the brother, युद्धाय for combat, अभिनियुक्तेन engaged, येन by whom, बिलस्य cave's, मुखम् entrance, पिहितम् blocked, सः he, धर्मम् morals, कथम् how, जानीते will he know?

M N Dutt

He that, while her son is living, appropriateth the beloved queen of his elder brother, mother to him by morality, is hated (of all beings). How can he that could cover up the mouth of the cave, when he had been desired by his brother gone on martial mission, to guard the same,—(how can he) know morality?

Summary

'He usurped his elder brother's queen, while he was still alive. It is morally abominable since an elder brother's wife is like a mother. How can a person who blocks the entrance of a cave while his noble brother is engaged in fighting inside be treated as righteous?
