उद्गिरंतो हि निगमान्विवाहसमये नृप । सर्वं निवेदयामासुः कर्णाटाय दुरात्मने
udgiraṃto hi nigamānvivāhasamaye nṛpa | sarvaṃ nivedayāmāsuḥ karṇāṭāya durātmane
विवाहसमये, नृप, निगमान् उद्गिरन्तः सर्वं वृत्तान्तं दुरात्मने कर्णाटाय न्यवेदयन्॥
Sūta (Lomaharṣaṇa) narrating to the sages (deduced; exact speaker not in snippet)
Even sacred occasions like marriage can be threatened when information is misused by the adharmic; vigilance protects dharma.
The larger context is Dharmāraṇya; this verse highlights events surrounding a wedding within that sacred setting.
The verse references Vedic recitation during the vivāha (marriage rite), but does not prescribe a specific additional ritual.
