الخامس يُنطق بنبرة سْفَريتَا؛ ومجاله الموسيقي هو الوسط (madhyama)، ونغمته تُعرف باسم نِشَذَه (Niṣadha). والمقطع «na» لونه أصفر ذهبي، وموضعه يُذكر في الوجه الشرقي—هكذا تُعلَّم مرتبته.
Suta Goswami (narrating traditional Shiva-mantra/varna-nyasa teaching within the Linga Purana)
It encodes a nyāsa-style mapping—sound (svara), note (niṣadha), color (pīta), and direction (east)—so the devotee installs mantra into the ritual body of the Linga, making worship an internalized, mantric consecration.
Shiva-tattva is presented as manifesting through śabda (sacred sound) ordered by cosmic correspondences; the Pati is approached not only as form (liṅga) but as the luminous intelligence structuring speech, direction, and ritual perception.
Varnamālā/akṣara-nyāsa linked to Linga-pūjā: assigning syllables with accent, pitch, color, and directional face, a practice that supports Pāśupata-style purification of the paśu by loosening pasha through disciplined mantra-placement.
