तुंबुरुर्ना रदश्चोभौ देवानामतिदुर्लभौ । नादरूपी शिवः साक्षान्नादतत्त्वविदौ हि तौ
tuṃbururnā radaścobhau devānāmatidurlabhau | nādarūpī śivaḥ sākṣānnādatattvavidau hi tau
Tumburu und Nārada—beide sind selbst unter den Göttern überaus selten. Denn Śiva selbst ist die Gestalt des Nāda, des heiligen Klanges, und jene zwei sind wahrlich Kenner des Prinzips des Nāda.
Skanda (deduced, Kāśīkhaṇḍa narrative frame)
Tirtha: Kāśī
Type: kshetra
Scene: Tumburu and Nārada depicted as celestial musicians, poised in reverent knowledge; behind them an abstract visualization of Śiva as vibrating nāda—concentric sound-waves emerging from a liṅga or from Śiva’s ḍamaru.
Mystic sound (Nāda) is divine; Śiva is identified with Nāda, and true musicians-sages are honored as knowers of that reality.
The teaching appears within the Kāśīkhaṇḍa setting, supporting Kāśī’s sanctity as a realm of Śiva and sacred sound.
No explicit ritual is given; the verse establishes a theological basis for devotional music and nāda-upāsanā.
