Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
भैक्ष्यं यवागूस्तक्रं वा पयो यावकमेव च फलमूलादि पक्वं वा कणपिण्याकसक्तवः
bhaikṣyaṃ yavāgūstakraṃ vā payo yāvakameva ca phalamūlādi pakvaṃ vā kaṇapiṇyākasaktavaḥ
Bagi yang memelihara disiplin Śaiva, makanan yang diizinkan ialah: makanan hasil sedekah (bhikṣā), yavāgū (bubur nasi), takra (susu mentega/air dadih), susu, dan yāvaka (olahan barli); juga buah-buahan dan akar-umbian yang dimasak, serta bijirin seperti kaṇa, piṇyāka (hampas minyak), dan saktu (tepung barli panggang).
Suta Goswami (narrating Śaiva-vrata rules to the sages of Naimiṣāraṇya)
It defines purified, restraint-based food options for a Śaiva vow, supporting bodily and mental śuddhi so the worshipper approaches the Liṅga with disciplined senses and a sattvic mind.
By prescribing simplicity and non-indulgence, it implies Śiva as Pati is realized through inner purification—reducing pasha (bondage) born of craving in the pashu (individual soul).
Āhāra-niyama (dietary restraint) as part of Śaiva-vrata/Pāśupata-style discipline—using simple foods (alms, milk products, barley, fruits, roots) to steady the mind for mantra and Liṅga-pūjā.
