मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity

ビーシュマは言った。「六日ごとに一度だけ食を取る苦行者は、ゴーメーダ（牛供犠）の果報に等しい、比類なき功徳を得る。この教えは、規律ある抑制—定まった苦行と節度ある生活—をダルマの道として讃え、その霊的報いを大いなる祭式の功業と同等とみなすのである。」

Educational Q&A
Rigorous self-restraint—here, eating only once every sixth day—is presented as a powerful dharmic practice whose spiritual merit can equal or surpass that of major sacrificial rituals, emphasizing inner discipline over external display.
In Bhishma’s instruction on dharma (Anushasana Parva), he enumerates vows and observances and states the reward for a particular ascetic regimen: a sage who follows this strict eating schedule gains the supreme fruit associated with the Gomeda sacrifice.
