लिङ्गार्चनपूर्वकं स्नानाचमनविधिः
Snana–Achamana as Preparation for Linga-Archana
अवगाह्य पुनस्तस्मिन् जपेद्वै चाघमर्षणम् तत्तोये भानुसोमाग्निमण्डलं च स्मरेद्वशी
avagāhya punastasmin japedvai cāghamarṣaṇam tattoye bhānusomāgnimaṇḍalaṃ ca smaredvaśī
After immersing again in that water, the disciplined practitioner should recite the Aghamarṣaṇa, the sin-dispelling mantra. And within that very water he should contemplate the circles of the Sun, the Moon, and Fire, bringing the senses under control; thus, by mantra and inner vision, the paśu is led from impurity toward Śiva’s purity.
Suta Goswami (narrating Shiva-puja vidhi within the Purva-Bhaga discourse)
It prescribes the preparatory purification for Shiva-puja: ritual bathing, Aghamarṣaṇa japa to remove pāpa and mala (impurity), and focused contemplation—so the worshipper approaches the Linga with inner and outer śuddhi.
By directing meditation on sun, moon, and fire as mandalas, it points to Shiva as the inner ground of all luminous powers—yet to be realized through discipline that loosens pāśa (bondage) upon the paśu.
A combined practice of snāna (immersion), mantra-japa (Aghamarṣaṇa), and dhyāna on bhānu-soma-agni maṇḍalas—an internalized purification aligned with Pāśupata-style sense-mastery (vaśitva).
