दशशैवव्रतप्रश्नः — Inquiry into the Ten Principal Śaiva Vratas
परिधाय शुभं वस्त्रमन्तर्वासश्शुभन्तथा । आचम्य च त्रिवारं हि पूजारंभं समाचरेत्
paridhāya śubhaṃ vastramantarvāsaśśubhantathā | ācamya ca trivāraṃ hi pūjāraṃbhaṃ samācaret
Having put on clean and auspicious outer garments, and likewise a pure inner cloth, one should perform ācamana three times and then duly commence the worship.
Suta Goswami
Tattva Level: pashu
Shiva Form: Mahadeva
Significance: Establishes external and internal purity (vastra-śuddhi, ācamanam) as a gateway to effective Śiva-arcana and mantra-siddhi.
It teaches that approaching Śiva begins with śauca (purity) and niyama (disciplined observance): by cleansing oneself and steadying intention, the devotee becomes fit to offer reverent worship to Pati (the Lord) and receive His grace.
Linga-worship is a sacred, ordered act in which the devotee meets Saguna Śiva through ritual form; clean clothing and ācamana establish ritual eligibility, ensuring the offerings and mantra are performed with proper reverence and purity before the Linga.
Perform ācamana three times and begin the puja in a purified state; as a practical takeaway, pair this with calm breath, mental recollection of Śiva, and then proceed to japa (such as Om Namaḥ Śivāya) and the formal offerings.
