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 ||
Dengan kedua-dua suku kata ini, tersusunlah bentuk mantra yang terdiri daripada lapan belas bahagian; rumusan suci itu menjadi mantra dua puluh suku kata. Ia boleh diterapkan pada batu Śālagrāma, pada permata, pada yantra upacara, dalam maṇḍala yang telah ditahbiskan, atau pada arca suci (pratimā) juga.
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.
