अन्नशुद्धौ सत्त्वशुद्धिर् न मृदा न जलेन वै सत्त्वशुद्धौ भवेत्सिद्धिस् ततो ऽन्नं परिशोधयेत्
annaśuddhau sattvaśuddhir na mṛdā na jalena vai sattvaśuddhau bhavetsiddhis tato 'nnaṃ pariśodhayet
അന്നത്തിന്റെ ശുദ്ധിയാൽ സത്ത്വശുദ്ധി ഉണ്ടാകുന്നു—മണ്ണിനാലോ ജലത്താലോ മാത്രം അല്ല. സത്ത്വം ശുദ്ധമായാൽ സിദ്ധി ലഭിക്കും; അതിനാൽ അന്നത്തെ പരിശുദ്ധമാക്കണം.
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.
