Śreyas and Paramārtha: The Ribhu–Nidāgha Teaching on Non-Dual Self
Advaita
स ऋभुस्तर्कयामास निदाघस्य नरेश्वर । देविकायास्तटे वीर नागरं नाम वै पुरम् ॥ ३८ ॥
sa ṛbhustarkayāmāsa nidāghasya nareśvara | devikāyāstaṭe vīra nāgaraṃ nāma vai puram || 38 ||
大王啊,圣者梨布(Ṛbhu)思惟尼达迦(Nidāgha),遂至勇武之城“那伽罗”(Nāgara),其地在德维迦河(Devikā)之滨。
Narada (narrating to Sanatkumara in the Moksha-dharma dialogue frame)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It sets the stage for a moksha-oriented instruction: the sage Ṛbhu’s deliberate approach toward Nidāgha signals the beginning of a teacher–student encounter meant to unfold knowledge of liberation (moksha) through discernment (tarka/vicāra).
This specific verse is primarily narrative and preparatory rather than explicitly devotional; it frames the setting for instruction. In the Narada Purana’s moksha-dharma context, such meetings often culminate in teachings that harmonize knowledge with devotion, but bhakti is not directly stated here.
No explicit Vedanga (like Vyākaraṇa, Jyotiṣa, or Kalpa) is taught in this line; it functions as a geographical and narrative locator (river bank, city name) before the philosophical teaching begins.
