Anūcāna (True Learning), the Vedāṅgas, and Śikṣā: Svara, Sāmavedic Chant, and Gandharva Theory
यक्षान्निषादः प्रीणाति भूतग्रामं च धैवतः । गानस्य तु दशविधा गुणवृत्तिस्तु तद्यथा ॥ ४३ ॥
yakṣānniṣādaḥ prīṇāti bhūtagrāmaṃ ca dhaivataḥ | gānasya tu daśavidhā guṇavṛttistu tadyathā || 43 ||
निषाद स्वर यक्षांना आनंदित करतो आणि धैवत स्वर भूतग्रामाला तृप्त करतो. आता गानाची गुणवृत्ती दहा प्रकारची सांगितली आहे—जशी पुढे आहे.
Sanatkumara (in instruction to Narada on technical sacred knowledge, Gandharva-veda)
Vrata: none
Primary Rasa: adbhuta
Secondary Rasa: shanta
It presents sacred sound (nāda) as a subtle force: specific swaras are said to harmonize and please particular classes of beings, showing that music can be used as a dharmic, sanctifying practice.
By implying that disciplined singing (gāna) has ordered, beneficial effects, it supports the bhakti principle that devotional sound—when properly formed—purifies the environment and makes worship more effective.
It aligns with Śikṣā and the technical tradition of Gandharva-veda: precise swara usage, their classifications, and their stated effects—introducing the forthcoming tenfold guṇa-vṛtti of singing.
