Mantra-Māhātmya and Sādhana of Kārtavīryārjuna
Nyāsa, Yantra, Homa, and Dīpa-Vrata
शेषाढ्यबीजयुग्मेन हृदयं विन्यसेदधः । शांतियुक्तचतुर्थेन कामाद्येन शिरोंऽगकम् ॥ ११ ॥
śeṣāḍhyabījayugmena hṛdayaṃ vinyasedadhaḥ | śāṃtiyuktacaturthena kāmādyena śiroṃ'gakam || 11 ||
With the pair of seed-syllables (bīja) endowed with the power of Śeṣa, one should place them below as hṛdaya-nyāsa (the heart placement). And with the fourth seed-syllable joined with “śānti”, from the series beginning with “kāma…”, one should place it upon the head as aṅga-nyāsa (the limb placement).
Sanatkumara (teaching Narada the technical mantra-nyāsa procedure)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches nyāsa—ritually placing specific bīja-syllables on body centers (heart and head) so the deity’s power is internalized and the practitioner’s speech, mind, and vital centers become aligned with the mantra.
Though technical, nyāsa supports bhakti by making worship embodied: the devotee consecrates the heart (seat of feeling) and head (seat of intention) so devotion is not merely verbal but ritually established within oneself.
It highlights ritual procedure (mantra-vidhi/nyāsa) and precise application of bīja formulas—an applied, technical discipline associated with correct recitation and placement used in structured worship.
