हिंसया ते प्रवर्तन्ते जपयज्ञो न हिंसया यावन्तः कर्मयज्ञाः स्युः प्रदानानि तपांसि च
hiṃsayā te pravartante japayajño na hiṃsayā yāvantaḥ karmayajñāḥ syuḥ pradānāni tapāṃsi ca
Those rites proceed through violence; but the sacrifice of japa does not proceed through violence. Whatever ritual sacrifices of action there may be—along with gifts (dāna) and austerities (tapas)—on the Śaiva path, offering japa with devotion to the Lord (Pati) frees the bound soul (paśu) from bondage (pāśa).
Suta Goswami (narrating the Linga Purana’s teaching to the sages at Naimisharanya)
It elevates inner offering—mantra-japa—as a non-violent yajna, fitting Linga-puja where devotion and purity of consciousness are primary over external, injury-linked rites.
Shiva as Pati is approached through sattvic, non-injurious worship; japa refines the paśu’s mind and loosens pāśa, making liberation-oriented devotion central to Shiva-tattva.
Japa-yajna—continuous mantra repetition as an internal sacrifice—aligned with Shaiva discipline and the Pashupata emphasis on transforming the practitioner through mantra and restraint.
