Shiva Purana — Rudra Samhita, Shloka 28
पार्वत्याः तपः-परीक्षा (Śiva Tests Pārvatī’s Austerity)
परार्थे च तपश्चेद्वै तिष्ठेत्तु तप एव तत् । रत्नं हस्ते समादाय हित्वा काचस्तु संचितः
parārthe ca tapaścedvai tiṣṭhettu tapa eva tat | ratnaṃ haste samādāya hitvā kācastu saṃcitaḥ
もし苦行（タパス）が他のため（すなわち世俗の利得や人を喜ばせるため）に行われるなら、それはただ「タパス」として留まり、最上の果は失われる。手に貴い宝珠を握りながらそれを捨て、代わりにガラス片を丹念に集めるようなものである。

FAQs
It teaches that austerity aimed at external approval or worldly ends is spiritually inferior; true tapas should be inwardly oriented toward Shiva-realization and liberation, otherwise one trades the “jewel” of moksha for the “glass” of temporary results.
Worship of the Linga (Saguna Shiva) is meant to purify intention and fix the mind on Shiva as the supreme goal; when tapas and worship are performed for boons alone, the act remains outward and misses the liberating grace that Linga-bhakti is meant to awaken.
Refine the sankalpa: perform japa of the Panchākṣarī (“Om Namaḥ Śivāya”), Linga-pūjā, and meditation with detachment—seeking purity and Shiva’s grace rather than social recognition or material gain.
