मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
एकोनत्रिंशे दिवसे यः प्राशेदेकभोजनम्,जो बारह महीनोंतक सदा सत्यव्रतके पालनमें तत्पर हो उन््तीसवें दिन एक बार भोजन करता है, उसे देवर्षियों तथा राजर्षियोंद्वारा पूजित दिव्य मंगलमय लोक प्राप्त होते हैं
ekonatriṁśe divase yaḥ prāśed ekabhojanam | yo dvādaśa māsān yāvat sadā satyavrate pālane tatparo bhavati, sa ekonatriṁśe dine ekavāraṁ bhuṅkte; tena devarṣibhiḥ rājarṣibhiś ca pūjitaṁ divyaṁ maṅgalamayaṁ lokaṁ prāpnoti ||
ビーシュマは言った。「十二か月のあいだ常に真実の誓戒（サティヤ・ヴラタ）を堅く守り、二十九日目には一度だけ食を取る者は、天の聖仙（デーヴァ・リシ）と王の聖仙（ラージャ・リシ）に礼拝される、吉祥なる神聖の世界に至る。ここでは、規律ある節制と揺るがぬ真実とが結び合わさって、高き霊的報いへ導く道であると讃えられている。」

Educational Q&A
Truthfulness sustained as a vow, combined with disciplined moderation in eating (single-meal observance on a specified day), is presented as a dharmic practice that yields exalted spiritual merit and access to auspicious celestial realms.
In Anushasana Parva, Bhishma continues instructing Yudhishthira on dharma by describing the fruits of specific vratas. Here he states the reward for a year-long commitment to satyavrata coupled with a regulated single-meal observance on the twenty-ninth day.
