ബ്രഹ്മയജ്ഞത്തിനായിട്ടേ പുണ്യമായ ആചമനം ചെയ്യേണ്ടത്. ഹേ വിപ്രന്മാരേ, ഋചകളുടെ പ്രീതിക്കായി മൂന്നു പ്രാവശ്യം ജലം സിപ്പ് ചെയ്ത് ഓരോ തവണയും വീണ്ടും വീണ്ടും വായ് കഴുകണം।
Suta Goswami (narrating Purāṇic injunctions to the sages of Naimiṣāraṇya)
It establishes ācamana as a mandatory act of ritual purity before Brahma-yajña and, by extension, before Shiva-pūjā to the Liṅga—purifying the devotee (paśu) so worship is offered in a fit state to Pati (Śiva).
Indirectly, it points to Śiva as the Pati who is approached through śuddhi (purification) and Vedic sanctity—suggesting that disciplined purity and reverence for mantra/ṛc align the paśu toward Shiva-tattva.
Ācamana performed three times with repeated rinsing—an external śauca practice that supports Vedic recitation (Brahma-yajña) and steadies the practitioner for Shaiva worship and Pāśupata-oriented discipline.
