The Exposition of the Krishna Mantra (Kṛṣṇa-mantra-prakāśa): Nyāsa, Dhyāna, Worship, Yantra, and Prayoga
आभ्यामष्टादशक्लिपः स्याद्विंशत्यक्षरो मनुः । शालग्रामे मणौ यंत्रे मंडले प्रतिमासु वा ॥ १६० ॥
ābhyāmaṣṭādaśaklipaḥ syādviṃśatyakṣaro manuḥ | śālagrāme maṇau yaṃtre maṃḍale pratimāsu vā || 160 ||
Par ces deux (syllabes), on agence une forme de mantra composée de dix-huit éléments; la formule sacrée devient un mantra de vingt syllabes. On peut l’appliquer sur une pierre de Śālagrāma, sur une gemme, sur un yantra rituel, dans un maṇḍala consacré, ou encore sur des images (pratimās).
Narada (teaching in the Vedanga/ritual-technical context to the Sanatkumara tradition)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It teaches that mantra-power is not only recited but also ritually installed on sacred supports (Śālagrāma, yantra, maṇḍala, images), making devotion and worship more tangible and rule-governed.
By permitting mantra-application to Śālagrāma and pratimās, it frames bhakti as disciplined worship where the devotee approaches the divine through sanctified forms and properly constructed mantras.
It highlights technical mantra-vidyā: counting and structuring akṣaras (syllables) and prescribing correct ritual loci (yantra/maṇḍala/pratimā) for mantra-installation.
