Anūcāna (True Learning), the Vedāṅgas, and Śikṣā: Svara, Sāmavedic Chant, and Gandharva Theory
तानरागस्वरग्राममूर्च्छनानां तु लक्षणम् । पवित्रं पावनं पुण्यं यथा तुभ्यं प्रकीर्तितम् ॥ २९ ॥
tānarāgasvaragrāmamūrcchanānāṃ tu lakṣaṇam | pavitraṃ pāvanaṃ puṇyaṃ yathā tubhyaṃ prakīrtitam || 29 ||
താന, രാഗ, സ്വര, ഗ്രാമ, മൂർച്ച്ഛന എന്നിവയുടെ ലക്ഷണങ്ങൾ നിനക്കു യഥാവിധി പ്രസ്താവിച്ചിരിക്കുന്നു. ഈ ഉപദേശങ്ങൾ പവിത്രവും പാവനവും പുണ്യപ്രദവും ആകുന്നു॥२९॥
Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It frames technical knowledge of sacred sound (tāna, rāga, svara, grāma, mūrcchanā) as spiritually purifying and merit-producing, not merely artistic or theoretical.
By emphasizing purity and punya gained through sacred instruction, it supports the Bhakti ethos that disciplined, sanctified sound and learning can become an offering and a purifier of the mind.
Śikṣā-related sound science and allied technical tradition: correct understanding of notes (svara), scale-systems (grāma), modal progressions (mūrcchanā), and melodic structures (rāga, tāna).
