औदर्यैर्व्याधिभिः सर्वैर् मासेनैकेन मुच्यते एकादशेन भुञ्जीयाद् अन्नं चैवाभिमन्त्रितम्
audaryairvyādhibhiḥ sarvair māsenaikena mucyate ekādaśena bhuñjīyād annaṃ caivābhimantritam
En mangeant une nourriture consacrée (imprégnée par le mantra), on se délivre en un mois de toutes les maladies issues des troubles du ventre. Cette nourriture sanctifiée doit être prise après l’observance de la discipline en onze points (ekādaśa-vidhi).
Suta Goswami (narrating Śaiva ritual discipline to the sages of Naimiṣāraṇya, drawing on internal Purāṇic instruction)
It presents Śiva-prasāda (mantra-empowered food) as a purifying support for the sādhaka—strengthening the body so the Pashu (individual soul) can steadily perform Liṅga-pūjā and progress toward Pati (Śiva).
Śiva is implied as the supreme purifier whose mantra transforms ordinary food into a sanctifying medium, loosening pasha (bondage) expressed even as bodily disorder and restoring harmony conducive to sādhanā.
The practice is consuming abhimantrita anna—food consecrated with Śiva-mantra—along with an ekādaśa (elevenfold) regimen of discipline, functioning as a vrata-based support to Śaiva sādhanā.
