संन्यासाचारवर्णनम्
Description of the Conduct and Daily Discipline of Saṃnyāsa
द्विराचम्य मृदा तोयैः कटिशौचं विधाय च । अरुणोदयकाले तु स्नानं कुर्यान्मृदा सह
dvirācamya mṛdā toyaiḥ kaṭiśaucaṃ vidhāya ca | aruṇodayakāle tu snānaṃ kuryānmṛdā saha
రెండుసార్లు ఆచమనం చేసి, మట్టి నీటితో కటిప్రదేశ శుద్ధి చేసి; అరుణోదయకాలంలో మట్టితో కూడ స్నానం చేయవలెను।

Tattva Level: pashu
Shiva Form: Sadāśiva
It teaches that outer purity (ācamana, cleansing, and dawn-bathing) supports inner purity, making the practitioner fit for Shiva-upāsanā where body, speech, and mind are aligned in sattva.
Linga worship in the Shiva Purana is preceded by śauca and snāna; preparing the body at dawn is a prerequisite for offering water, bilva, and mantra-japa to Saguna Shiva in the form of the Linga.
Perform ācamana, maintain bodily cleanliness, and bathe at aruṇodaya; this becomes the foundation for subsequent Shaiva practices such as applying bhasma/tripuṇḍra and chanting the Pañcākṣarī (Om Namaḥ Śivāya).
