Educational Q&A

The verse emphasizes the sanctity and precision of Vedic invocation: divine powers and ritual principles are properly approached through established names and paired appellations, especially within the Sāma-chanting tradition.

Nārada is listing or identifying sacred entities and Vedic-ritual designations—Mantras, a prominent Sāman (Rathantara), specific named powers (Harimān, Vasumān), and the Ādityas with Indra—describing how they are traditionally invoked and referred to.
