Anūcāna (True Learning), the Vedāṅgas, and Śikṣā: Svara, Sāmavedic Chant, and Gandharva Theory
विस्तरं विरसं चैव विश्लिष्टं विषमाहतम् । व्याकुलं तालहीनं च गीतिदोषाश्चतुर्दश ॥ ४५ ॥
vistaraṃ virasaṃ caiva viśliṣṭaṃ viṣamāhatam | vyākulaṃ tālahīnaṃ ca gītidoṣāścaturdaśa || 45 ||
Terlalu memanjang (ditarik-tarik), tanpa rasa keindahan, terpecah-pecah, dipukul tidak merata, gelisah, dan tanpa tāla—ini (dan lainnya) termasuk empat belas cacat dalam nyanyian (gīti).
Sanatkumara (in dialogue instructing Narada on disciplined sacred practice and technical correctness)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It teaches that sacred sound—whether mantra, stotra, or devotional singing—must be disciplined and well-formed; careless delivery (without rasa, coherence, or tāla) becomes a ‘fault’ that diminishes the sanctifying power of worship.
Bhakti is not only emotion but also right offering: devotional song should be steady, coherent, and rhythmically grounded, so the mind becomes one-pointed rather than ‘vyākula’ (agitated).
Śikṣā (phonetics and disciplined vocal delivery) and allied concerns of rhythm/measure (tāla) are emphasized—practical rules for correct recitation and performance so that sacred sound remains precise and effective.
