The Description of the Four Durgā Mantras
शिरोवदनहृद्गुह्यपादेषु विधिना न्यसेत् । हृल्लेखां गगनां रक्तां भूयो मन्त्री करालिकाम् ॥ ११० ॥
śirovadanahṛdguhyapādeṣu vidhinā nyaset | hṛllekhāṃ gaganāṃ raktāṃ bhūyo mantrī karālikām || 110 ||
According to the prescribed procedure, one should perform nyāsa upon the head, face, heart, secret region, and feet. Then the mantra-practitioner should again mentally place the heart-inscription (hṛllekhā)—the red syllable ‘ga’ (gaganā)—and thereafter place ‘karālikā’ as well.
Narada (teaching ritual procedure in a technical/vidhi section)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It teaches nyāsa—ritualized placement of mantra-power on specific body-points—so the practitioner internalizes the deity/mantra, making the body a sanctified support for worship and meditation.
Though technical, it supports bhakti by training concentrated remembrance and reverent embodiment of the mantra; devotion becomes disciplined, continuous, and inwardly established through prescribed placements.
Ritual procedure (vidhi) and mantra-application techniques—especially nyāsa and color/seed-syllable visualization—typical of technical instruction found in the Third Pada’s applied sacred sciences.
