Sound itself is directly the body of Brahman—the revealer of the Śabda-Brahman. It is constituted of letters and their parts, marked by the unmanifest (avyakta), and yet it abides in many modes.
Suta Goswami
It frames Linga devotion as rooted in mantra and sacred sound: the Linga is approached not only as form but as Śabda-Brahman, where worship begins with vibration (nāda) and articulated varṇas.
Shiva-tattva is indicated as the Pati who is both unmanifest (avyakta) and manifest as revelatory sound—present in many modes, yet grounded in the subtle source beyond ordinary perception.
Mantra-centric practice: japa, śravaṇa of sacred sound, and nāda-upāsanā as a Pāśupata-oriented discipline that refines the paśu (soul) by loosening pāśa (bondage).
