देवद्रोहं गुरुद्रोहं न कुर्यात्सर्वयत्नतः कृत्वा प्रमादतो विप्राः प्रणवस्यायुतं जपेत्
devadrohaṃ gurudrohaṃ na kuryātsarvayatnataḥ kṛtvā pramādato viprāḥ praṇavasyāyutaṃ japet
देवद्रोहं गुरुद्रोहं सर्वयत्नेन नाचरेत्। कृत्वा प्रमादतो यस्तु, विप्राः, प्रणवस्यायुतं जपेत्॥
Suta Goswami (narrating puranic instruction to the sages; internal source framed as dharma-teaching)
It safeguards Linga-pūjā by stressing aparādha-avoidance—betraying Devas or the Guru undermines mantra-adhikāra; Praṇava-japa is prescribed as a purificatory remedy to restore ritual fitness.
By elevating the Praṇava (Oṁ)—a primary marker of the Supreme (Pati)—as the expiatory support, it implies that returning to the foundational vibration of Shiva-tattva purifies the pashu (soul) from pasha (bondage) created by offence and negligence.
Mantra-japa of the Praṇava (Oṁ), specifically ten thousand repetitions, as prāyaścitta—an inner purification practice aligned with Shaiva discipline and preparatory to stable pūjā and yogic steadiness.
