नारायणं चक्रमतस्तत्त्वानि द्वादशैव तु । मूलार्णहृत्परायाद्यमात्मने हृदयांतिमम् ॥ ८० ॥
nārāyaṇaṃ cakramatastattvāni dvādaśaiva tu | mūlārṇahṛtparāyādyamātmane hṛdayāṃtimam || 80 ||
For Nārāyaṇa—the Lord who bears the discus (cakra)—there are indeed twelve principles (tattvas). Beginning from the root syllable (mūla-arṇa) and culminating in the heart’s innermost essence, they are directed to the Self (Ātman).
Narada (teaching within the Narada–Sanatkumara dialogue framework)
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: shanta
It frames Nārāyaṇa-upāsanā as a structured inner ascent: from the mantra’s root-syllable (bīja) through graded principles (tattvas) to realization centered in the heart, oriented toward the Self.
Bhakti here is disciplined worship: devotion to Nārāyaṇa (the cakra-bearing Lord) expressed through mantra-japa and inward contemplation, bringing the devotee from sound (mūlārṇa) to heartfelt absorption (hṛdaya).
It reflects mantra-vidyā and phonetic/semantic discipline—key to Śikṣā (sound/recitation) and Vyākaraṇa/Nirukta-style attention to syllables and meaning—applied to meditation on bīja, tattva, and heart-centered upāsanā.
