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.
