उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
संध्यातिक्रमणाद्विप्रो ब्राह्मण्यात्पतते यतः असत्यं न वदेत् किंचिन् न सत्यं च परित्यजेत्
saṃdhyātikramaṇādvipro brāhmaṇyātpatate yataḥ asatyaṃ na vadet kiṃcin na satyaṃ ca parityajet
ସନ୍ଧ୍ୟାକର୍ମ ଅତିକ୍ରମ କଲେ ଦ୍ୱିଜ ବ୍ରାହ୍ମଣ୍ୟରୁ ପତିତ ହୁଏ; ତେଣୁ ସେ କିଛିମାତ୍ର ଅସତ୍ୟ ନ କହୁ, ଓ ସତ୍ୟାଚରଣ କେବେ ତ୍ୟାଗ ନ କରୁ।

It establishes ethical and daily-ritual purity—especially Sandhyā observance and truthfulness—as foundational qualifications for Shiva-upāsanā, making the devotee fit for steadiness in Linga-pūjā.
Implicitly, it presents Shiva as Pati who responds to inner purity: when the pashu reduces pasha through satya and nitya-karma, the ground is prepared for Śiva’s anugraha (grace).
Sandhyā-vandana (daily twilight worship) is highlighted as essential nitya-karma, paired with satya as a disciplined vow that supports purification and spiritual fitness for Shaiva practice.
