मत्स्यगृह्यस्य यत्पापं षण्मासाभ्यन्तरे भवेत् एकाहं तत्समं ज्ञेयम् अपूतं यज्जलं भवेत्
matsyagṛhyasya yatpāpaṃ ṣaṇmāsābhyantare bhavet ekāhaṃ tatsamaṃ jñeyam apūtaṃ yajjalaṃ bhavet
Apa jua dosa yang terkumpul bagi orang yang menyimpan ikan di dalam rumah selama enam bulan—ketahuilah bahawa kadar cela yang sama timbul hanya dalam satu hari apabila air yang digunakan masih tidak disucikan.
Suta Goswami (narrating Purana injunctions to the sages of Naimisharanya)
It elevates jala-śuddhi (purified water) as essential for Linga-pūjā, warning that using impure water quickly accumulates pāpa and obstructs the efficacy of worship.
By implication, Shiva as Pati is supremely pure (śuddha); approaching Him through the Linga requires the sādhaka (pashu) to reduce pasha (impurity/bondage) through disciplined śauca and correct ritual means.
Ritual śauca—especially purification and proper handling of water for abhiṣeka and daily worship—underscoring that external purity supports inner Pāśupata discipline.
