The Exposition of the Krishna Mantra (Kṛṣṇa-mantra-prakāśa): Nyāsa, Dhyāna, Worship, Yantra, and Prayoga
अष्टादशार्णो मंत्रोऽयं दुर्गाधिष्ठातृदैवतः । नारदोऽस्य मुनिश्छंदो गायत्री देवता पुनः ॥ ७ ॥
aṣṭādaśārṇo maṃtro'yaṃ durgādhiṣṭhātṛdaivataḥ | nārado'sya muniśchaṃdo gāyatrī devatā punaḥ || 7 ||
This is an eighteen-syllabled mantra, presided over by Durgā as its governing deity. For it, Nārada is the seer (ṛṣi), the meter is Gāyatrī, and the invoked deity is again declared to be Gāyatrī.
Narada (teaching in a technical/mantra-śāstra context within the Vedanga-oriented section)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It gives the essential mantra-anukramaṇī details—syllable-count, presiding deity, seer (ṛṣi), and meter (chandas)—which are considered necessary for precise and effective mantra-japa and ritual application.
It frames devotion as disciplined worship: Bhakti here is practiced through correctly oriented mantra-recitation, acknowledging the mantra’s deity (Durga) and its Vedic parameters (ṛṣi and chandas).
Chandas (Vedic meter) and mantra-vidhi are highlighted—specifically, how a mantra is authenticated and applied by stating its ṛṣi (Narada), chandas (Gāyatrī), and devatā (Durga/Gāyatrī) in a technical format.
