Skanda (deduced)
Scene: A group of brāhmaṇas conferring, one holding a water-pot and kuśa grass, another reading a record; their faces show focused diligence; the ritual space is prepared with cleanliness and order.
Ritual acts should be performed with conscientious care; diligence is itself a form of dharma.
No specific tīrtha is mentioned in this line.
Brāhmaṇas conducting śuddhi-karma must diligently verify the relevant person(s) in the lineage.
