It teaches that a mantra becomes spiritually and ritually effective only after proper saṃsādhana (disciplined accomplishment); only then is it eligible for prayoga, after which the text proceeds to concrete worship aids like a yantra.
It frames devotion as regulated upāsanā: sincere practice culminates in a “ready” mantra, and worship then becomes structured through prescribed forms (like a pūjā-yantra), aligning inner bhakti with outer ritual order.
Ritual-technical knowledge: the distinction between mantra-saṃsādhana (perfection) and mantra-prayoga (application), and the use of yantra as a precise aid in pūjā—typical of Vedāṅga-aligned procedural instruction.
