Sadācāra–Varṇa-lakṣaṇa and Prātaḥkṛtya
Right Conduct, Social Typologies, and Morning Purification
निशांत्यायामोषा ज्ञेया यामार्धं संधिरुच्यते । तत्काले तु समुत्थाय विण्मूत्रे विसृजेद्द्विजः
niśāṃtyāyāmoṣā jñeyā yāmārdhaṃ saṃdhirucyate | tatkāle tu samutthāya viṇmūtre visṛjeddvijaḥ
रात्रीच्या शेवटचा काळ ‘उषा’ म्हणून ओळखला जातो; अर्ध यामाचा काळ ‘संधी’ म्हणतात. त्या वेळी उठून द्विजाने मल‑मूत्राचा त्याग करावा.

Tattva Level: pashu
Shiva Form: Sadāśiva
Significance: General: emphasizes śauca (purity) at the sandhi of night and day; such bodily purification is treated as prerequisite for temple entry, liṅga-sevā, and mantra-japa.
It teaches śauca (purity) and disciplined timing: rising at dawn-sandhi and completing bodily purification is presented as the proper foundation for later Sandhyā, japa, and Shiva-pūjā—outer order supporting inner steadiness on the path to moksha.
Linga-worship emphasizes cleanliness and readiness of body-mind; by instructing purification at dawn-sandhi, the text aligns the devotee with an auspicious time for approaching Saguna Shiva in ritual, so the subsequent offerings, mantra-japa, and meditation are done without impurity.
A practical dinācārya step: rise at dawn-sandhi (uṣā), attend to natural elimination and cleanliness first, and then proceed to Sandhyā, Shiva mantra-japa (such as the Pañcākṣarī), and worship with a purified body and focused mind.
