वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
मातृहा पितृहा चैव वीरहा भ्रूणहा तथा संवत्सरं क्रमाज्जप्त्वा त्रिसंध्यं शङ्कराश्रमे
mātṛhā pitṛhā caiva vīrahā bhrūṇahā tathā saṃvatsaraṃ kramājjaptvā trisaṃdhyaṃ śaṅkarāśrame
即便是弑母者、弑父者、杀勇士者、害胎者——若住于商羯罗(Śaṅkara)之道场,依次第于三时交会(黎明、正午、黄昏)如法持诵(japa)满一年,亦能以对主宰帕提(Pati,湿婆)的奉爱而得清净;因为重罪之系缚(pāśa)将被其真言修持之律所斩断。
Suta Goswami (narrating the Śaiva prāyaścitta teaching within the Purva-bhāga discourse)
It frames severe sin as removable through disciplined Śiva-oriented practice—year-long mantra-japa at the three sandhyās—implying that turning to Pati (Śiva) via regulated sādhana is central to purification and eligibility for Śaiva worship.
Śiva is implied as Pati—the liberating Lord whose mantra and āśrama-discipline can sever pāśa (bondage) even when karmic impurity is extreme, highlighting His grace working through rule-bound practice.
Trisaṃdhyā mantra-japa for one full year, performed in proper order under Śaṅkara-āśrama discipline—an ascetic, Pāśupata-leaning regimen of daily regulated repetition as prāyaścitta.
