Mantra-Māhātmya and Sādhana of Kārtavīryārjuna
Nyāsa, Yantra, Homa, and Dīpa-Vrata
वर्मास्त्राभ्यामस्त्रमुक्तं शेषार्णैर्व्यापकं पुनः । हृदये जठरे नाभौ जठरे गुह्यदेशतः ॥ १३ ॥
varmāstrābhyāmastramuktaṃ śeṣārṇairvyāpakaṃ punaḥ | hṛdaye jaṭhare nābhau jaṭhare guhyadeśataḥ || 13 ||
Having thus discharged the Astra (weapon-mantra) together with the Varma (armour-mantra), one should again perform the all-pervading protective nyāsa with the remaining syllables—placing them in the heart, in the belly, at the navel, again in the belly, and in the secret region below.
Sanatkumara (in instruction to Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches a disciplined method of inner protection: by placing mantra-syllables into key bodily centers, the practitioner ritualizes awareness and invokes a ‘vyāpaka’ (all-covering) safeguard.
Though technical, the practice supports Bhakti by creating a protected, focused inner field for worship—so the devotee’s mind and senses remain steady for sustained remembrance and mantra-japa.
It highlights applied mantra-vidhi and nyāsa (ritual placement), a technical discipline closely tied to correct phonetic syllable-use (Śikṣā) and precise ritual procedure (Kalpa).
