जपेन पापं शमयेदशेषं यत्तत्कृतं जन्मपरंपरासु /* जपेन भोगान् जयते च मृत्युं जपेन सिद्धिं लभते च मुक्तिम्
japena pāpaṃ śamayedaśeṣaṃ yattatkṛtaṃ janmaparaṃparāsu /* japena bhogān jayate ca mṛtyuṃ japena siddhiṃ labhate ca muktim
Por el japa (repetición del mantra) se apacigua por completo todo pecado, cualquiera que se haya acumulado a través de nacimientos sucesivos. Por el japa se trascienden los goces de los sentidos y aun se vence a la muerte; por el japa se obtienen los siddhi y, al final, se alcanza la liberación (mokṣa) bajo el Señor, el Pati, Śiva.
Suta Goswami (narrating to the sages of Naimisharanya)
It establishes japa as a primary limb of Linga-upāsanā: by repeating Shiva-mantras with devotion, the pashu (soul) is purified of pāpa across lifetimes and becomes fit for Shiva’s grace that culminates in mokṣa.
By presenting liberation as the fruit of japa, it implies Shiva as Pati—the supreme Lord who removes pāśa (bondage) and grants both siddhi and final release, transcending even death for the devoted practitioner.
Mantra-japa (especially Shiva-mantra japa) as a Pāśupata-oriented sādhana: steady repetition that purifies karma, restrains bhoga-attachment, and supports yogic realization leading to siddhi and mokṣa.
