Indra’s Account: Shilada’s Tapas and Shiva’s Manifestation as Nandi
निर्मांसरुधिरत्वग् वै निर्लेपः कुड्यवत् स्थितः अस्थिशेषो ऽभवत्पश्चात् तममन्यत शङ्करः
nirmāṃsarudhiratvag vai nirlepaḥ kuḍyavat sthitaḥ asthiśeṣo 'bhavatpaścāt tamamanyata śaṅkaraḥ
肉も血も皮も失い、彼は汚れなく、壁のように動かず立っていた。やがて骨の名残のみとなったとき、シャンカラ(シヴァ)は彼を、あらゆる覆いを超えた「我が真の姿」として認められた。
Suta Goswami (narrating the Purana; describing Shiva’s recognition within the episode)
It points to Shiva as nirlepa—unstained by material coverings—supporting Linga worship as adoration of the formless Pati beyond the perishable body and its layers.
Shiva-tattva is shown as changeless and untouched (nirlepa), recognized when all transient coverings fall away—indicating the Supreme Pati who remains when pasha-bound appearances dissolve.
A vairagya-driven contemplative practice aligned with Pashupata Yoga: meditating on the impermanence of bodily layers and abiding in the unstained witness, the Shiva-nature beyond identification.
