It teaches that mantra-sādhana is completed by dhyāna: after bodily placement/nyāsa, the sādhaka must inwardly visualize the mantra’s presiding deity with precise iconographic marks, making the mantra a living presence rather than mere sound.
By directing the practitioner to contemplate the mantra-devatā’s form and attention (listening to śuka-ukti), it frames practice as personal devotion—relating to the deity through focused remembrance and reverent visualization.
Ritual application of mantra through nyāsa and dhyāna is emphasized—technical procedure (prayoga) and correct mental visualization, aligning with auxiliary disciplines used in mantra-śāstra and ritual practice.
