संध्याचरित्रवर्णनम् (Sandhyā-caritra-varṇanam) — “Narration of Sandhyā’s Austerity and Encounter with Śiva”
यदा त्वं दारुणं संध्ये तपश्चरसि पर्वते । यावच्चतुर्युगं तस्य व्यतीते तु कृते युगे
yadā tvaṃ dāruṇaṃ saṃdhye tapaścarasi parvate | yāvaccaturyugaṃ tasya vyatīte tu kṛte yuge
నీవు పర్వతంపై ప్రాతః–సంధ్యల పవిత్ర సంధికాలాలలో ఘోర తపస్సు చేయునప్పుడు, నాలుగు యుగాల కాలము గడిచిన తరువాత—గతమైన కృతయుగంలో నియత ఫలము నిశ్చయంగా ప్రాప్తమగును।
Lord Shiva (addressing Sati in the Sati Khanda narrative, as relayed by Suta Goswami)
Tattva Level: pashu
Shiva Form: Mahādeva
Sthala Purana: Not a Jyotirliṅga episode; the verse frames Satī’s destined tapas across yuga-cycles as the karmic/daivic timing for later events in Dakṣa’s line.
Significance: General teaching: sandhyā-tapas and mountain-austerity as a means to ripen divine destiny and receive Śiva’s anugraha.
Shakti Form: Satī
Role: liberating
Cosmic Event: caturyuga-span / yuga-cycle timing (Kṛta-yuga reference)
The verse highlights disciplined tapas at the sandhyā (dawn/dusk) as a powerful purifier of bondage (pāśa). In a Shaiva Siddhanta lens, such austerity ripens the soul (paśu) for Shiva’s grace (anugraha), indicating that spiritual fruition unfolds according to cosmic timing (yuga-dharma) as well as inner readiness.
Though the verse speaks directly of tapas, its devotional frame is Saguna Shiva—approaching the Lord through time-disciplined practice. In Shiva Purana practice, sandhyā worship commonly includes Linga-abhiṣeka, japa of the Panchākṣarī (Om Namaḥ Śivāya), and meditation, aligning austerity with concrete acts of Shiva-upāsanā.
A practical takeaway is sandhyā-sādhana: at dawn and dusk, sit in meditation, perform japa of “Om Namaḥ Śivāya,” and, where applicable, worship Shiva with bhasma (tripuṇḍra) and rudrākṣa as supports for steadiness and purity.
