The Exposition of the Krishna Mantra (Kṛṣṇa-mantra-prakāśa): Nyāsa, Dhyāna, Worship, Yantra, and Prayoga

In the central and outer angles of the lotus-diagram (the enclosure called the “city of fire”), one should inscribe in the pericarp the Kāma-bīja together with the intended aim (sādhya). Upon the petals one should place the six-syllabled mantra, the “enemy of the six openings,” which restrains the six gates of the senses. Then, placing Śakti and Śrī in front, one should write the mind-protecting syllables arranged as twice nine letters; and within the intermediate coverings, one should inscribe—each in due order upon the lotus—the ten letters ending with the tenth, and the excellent Anuvarya’s ten-letter mantra, one by one.

It presents a precise mantra–yantra procedure: placing specific bījas and protective syllables in the lotus’s pericarp, petals, and enclosures so that the sādhaka’s intention is supported by controlled senses and stabilized mind.
Though technical, the structure assumes surrender to divine Śakti and Śrī and disciplined sense-restraint; such inner order is treated as supportive to focused worship and remembrance, which are core to bhakti-oriented practice.
Ritual-technical knowledge: mantra-nyāsa, syllabic mapping (akṣara-vinyāsa), and diagrammatic placement (yantra-lekhana) used for protective and goal-oriented rites—typical of the Purana’s technical-science material in Book 1.3.
