भुवनकोशस्वभाववर्णनम् — सप्तद्वीप-पर्वत-लोकविन्यासः तथा यक्ष-उमा-प्रकाशः

そのヤクシャ(Yakṣa)を見たとき、相のしるし無きように見えても、まことは主であると悟り、インドラを伴う神々は「これはここに何であるか」と叫んだ。真実を確かめんとしてヤクシャに近づくと、アグニ(Agni)らは自らの力が衰え尽きたことを知った—予想をも超えて。
Suta Goswami (narrating the Devas’ encounter within the Purana’s frame)
It teaches that Shiva (Pati) may appear without outward “marks,” yet remains the Supreme; Linga worship trains the devotee to recognize the formless Lord beyond appearances and ego-based certainty.
Shiva-tattva is shown as transcendent and self-concealing: even the Devas cannot gauge Him by ordinary signs, and their limited powers collapse before His higher reality.
The key practice is inner surrender (śaraṇāgati) and humility—central to Shaiva sādhanā and Pāśupata orientation—recognizing that siddhis or divine powers are secondary to realizing Pati.
