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 ||
Con estas dos (sílabas) se dispone una forma de mantra compuesta de dieciocho partes; la fórmula sagrada se vuelve un mantra de veinte sílabas. Puede aplicarse sobre una piedra de Śālagrāma, sobre una gema, sobre un yantra ritual, en un maṇḍala consagrado o también sobre imágenes (pratimās).

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.
