संध्याचरित्रवर्णनम् (Sandhyā-caritra-varṇanam) — “Narration of Sandhyā’s Austerity and Encounter with Śiva”
तपसा सत्समो नास्ति न भूतो न भविष्यति । येन यज्ञस्समारब्धो ज्योतिष्टोमो महाविधिः
tapasā satsamo nāsti na bhūto na bhaviṣyati | yena yajñassamārabdho jyotiṣṭomo mahāvidhiḥ
Tiada kebajikan suci yang menyamai tapa (tapas)—tidak pernah ada pada masa lampau dan tidak akan ada pada masa hadapan—kerana dengan tapa, korban Jyotiṣṭoma yang agung, menurut tata-aturan yang besar, dapat dimulakan dan dijalankan dengan sempurna.

It declares tapas (disciplined austerity) as the highest purifier and enabler of dharma—surpassing other merits—because it refines the seeker’s intention and capacity for sacred action, aligning the soul toward Shiva’s grace and liberation.
In Shaiva practice, outer worship gains depth through inner tapas—vows, restraint, and steady devotion—so Linga worship is not merely ritual but a disciplined offering of the self, making the worship fit to receive Shiva’s presence (Saguna) and realize His transcendent nature (Nirguna).
Adopt tapas as a vrata: fasting or regulated diet, celibacy/restraint, truthfulness, and daily japa of Shiva’s name (especially the Panchakshara, “Om Namaḥ Śivāya”), supporting any puja or observance with disciplined consistency.
