Mahabharata — Anushasana Parva, Shloka 99
मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
रमते देवकन्याभिर्दिव्याभरण भूषित: । जो बारह महीनोंतक प्रतिदिन अग्निहोत्र करता हुआ बाईसवाँ दिन प्राप्त होनेपर एक बार भोजन करता है तथा अहिंसामें तत्पर

ビーシュマは言った。「第二十三日に一日に一度だけ食を取る者——長きにわたり日々アグニホートラを修し、アヒンサーに励み、賢明で、真実を語り、他人の過失をあげつらわぬ者——その者は太陽のごとく輝く姿を得る。最上の天の車（ヴィマーナ）に乗ってヴァスたちの世界へ赴き、そこで意のままに遊行し、甘露を飲んで生き、天の宝飾に飾られて天女たちと歓楽する。」

Educational Q&A
Sustained religious discipline (such as regulated eating and daily Agnihotra) must be paired with ethical virtues—especially non-violence, truthfulness, and freedom from fault-finding. When austerity and character align, the text portrays a high karmic fruit: radiant transformation and attainment of a divine realm.
Bhishma is describing the results of a specific observance: the practitioner eats only once on the prescribed day (here, the twenty-third), while maintaining Agnihotra and moral virtues. The narrative then depicts the promised outcome—ascending in a celestial vehicle to the realm of the Vasus, enjoying ambrosia and the company of heavenly maidens.
