अन्नशुद्धौ सत्त्वशुद्धिर् न मृदा न जलेन वै सत्त्वशुद्धौ भवेत्सिद्धिस् ततो ऽन्नं परिशोधयेत्
annaśuddhau sattvaśuddhir na mṛdā na jalena vai sattvaśuddhau bhavetsiddhis tato 'nnaṃ pariśodhayet
Từ sự thanh tịnh của thức ăn phát sinh sự thanh tịnh của sattva trong nội tâm—không chỉ do đất hay do nước. Khi sattva trở nên thanh tịnh, siddhi (thành tựu tâm linh) được thành tựu; vì vậy hãy thanh lọc thức ăn của mình.
Suta Goswami (narrating Shiva-oriented discipline within the Purva-Bhaga teaching stream)
It teaches that successful Shiva-puja and its fruits depend on sattva-śuddhi, and that sattva is stabilized primarily through purified food (āhāra), not only through external washing.
Shiva-tattva is approached through inner refinement: when the pashu’s sattva is purified, the veils of pasha loosen and siddhi becomes possible—indicating Shiva is realized through inward clarity rather than mere external ritual.
Āhāra-śuddhi as a core limb of Shaiva discipline: regulating and sanctifying food to purify sattva, supporting Pashupata-oriented practice and making worship, japa, and dhyāna effective.
