The Exposition of the Krishna Mantra (Kṛṣṇa-mantra-prakāśa): Nyāsa, Dhyāna, Worship, Yantra, and Prayoga
मंत्रेण पुटितांश्चापि प्रणवाद्यांस्ततो न्यसेत् । गायत्र्या पुटुतं मंत्रं विन्यसेन्मातृकास्थले ॥ ३४ ॥
maṃtreṇa puṭitāṃścāpi praṇavādyāṃstato nyaset | gāyatryā puṭutaṃ maṃtraṃ vinyasenmātṛkāsthale || 34 ||
Ensuite, qu’on établisse (par nyāsa) les syllabes commençant par le Praṇava (Oṃ), « scellées » (pūṭita) par le mantra. Et le mantra fortifié par la Gāyatrī doit être installé au siège des Mātṛkās, la matrice des lettres.

It teaches that mantra-power is stabilized through samskāra (puṭa/“sealing”) and nyāsa—internalizing sacred sound (Praṇava and the letter-matrix) so the practitioner’s body-mind becomes a fit locus for worship and realization.
By prescribing disciplined installation of Praṇava and the Gāyatrī-empowered mantra, it frames devotion as a sanctified practice: the devotee prepares oneself as an abode of the deity through purified sound and correct ritual placement.
It highlights mantra-vidyā and phonetic/letter awareness (linked to Śikṣā and the Mātṛkā alphabet tradition), emphasizing correct ritual application of syllables (Praṇava, Gāyatrī) via nyāsa.
