मत्स्यगृह्यस्य यत्पापं षण्मासाभ्यन्तरे भवेत् एकाहं तत्समं ज्ञेयम् अपूतं यज्जलं भवेत्
matsyagṛhyasya yatpāpaṃ ṣaṇmāsābhyantare bhavet ekāhaṃ tatsamaṃ jñeyam apūtaṃ yajjalaṃ bhavet
បាបណាដែលកើតឡើងចំពោះអ្នកដែលរក្សាត្រីនៅក្នុងផ្ទះរយៈពេលប្រាំមួយខែ—ចូរដឹងថា បាបមានទំហំដូចគ្នានោះ កើតឡើងក្នុងតែមួយថ្ងៃ បើទឹកដែលប្រើនៅតែមិនបានបរិសុទ្ធ។

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.
