मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
यस्तु संवत्सरं भुड्क्ते नवमे नवमे5हनि,जो एक वर्षतक नौ-नौ दिनपर एक समय भोजन करता है और बारहों महीने प्रतिदिन अग्निमें आहुति देता है, उसे एक हजार अश्वमेध यज्ञका परम उत्तम फल प्राप्त होता है
yastu saṁvatsaraṁ bhuṅkte navame navame 'hani, sa eka-varṣaṁ yāvat nava-nava-dine ekakālaṁ bhojanaṁ karoti dvādaśa-māsān pratidinam agnau āhutiṁ dadāti; tasmai sahasrāśvamedha-yajñānāṁ paramottamaṁ phalaṁ prāpyate.
ビーシュマは言った。「一年のあいだ九日ごとに一度だけ食し、十二か月のあいだ毎日、聖なる火に供物を捧げる者—その規律ある人は、千のアシュヴァメーダ（Aśvamedha）祭に等しい、最上の功徳を得る。」

Educational Q&A
Sustained self-control (eating only once every ninth day) combined with unwavering daily sacred duty (offering oblations into the fire) is praised as extraordinarily meritorious—ethically elevating inner discipline and consistent practice above mere display, equating it with the fruit of grand royal sacrifices.
In Bhishma’s instruction on dharma, he describes a specific year-long vow of regulated eating and daily fire-offerings, then states the resulting spiritual merit: the highest fruit comparable to that of a thousand Aśvamedha sacrifices.
