プラナヴァに始まる三種の作法に従い、神格を心臓・秘所・足・頭頂・言葉(発声)・そして喉にも安置してニヤーサを行うべきである。
Suta Goswami (narrating Shiva-oriented ritual teaching within the Linga Purana tradition)
It teaches inner Linga-worship through mantra-nyāsa: installing Shiva in key subtle-body centers so the external pūjā becomes grounded in direct Pati-awareness rather than mere outer offering.
Shiva is presented as immanent and installable as the indwelling Lord (Pati) across heart, speech, and vital centers—showing that Shiva-tattva pervades the pashu’s embodied field and can be realized through disciplined mantra.
Mantra-nyāsa beginning with Praṇava (Oṁ), applied in a threefold manner, aligning body and speech as instruments of Pashupata-style purification and concentration.
