मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
स लोकान् विपुलान् रम्यानादित्यानामुपाश्षुते । जो लगातार बारह महीनेतक पूरे बीस दिनपर एक बार भोजन करता
sa lokān vipulān ramyān ādityānām upāśnute |
ビーシュマは言った。そのような者は、アーディティヤ（太陽神群）の広大で麗しい世界に至る。十二か月のあいだ絶えず、二十日に一度だけ食し、真実を語り、誓戒を守り、肉を断ち、ブラフマチャリヤ（梵行・禁欲）を保ち、あらゆる生きものの利益に尽くす者は、太陽神の広く美しい領域へと赴くのである。

Educational Q&A
The verse teaches that rigorous self-discipline—truthfulness, faithful observance of vows, abstention from meat, celibacy, and active commitment to the welfare of all beings—produces spiritual merit culminating in attainment of exalted solar realms (the worlds of the Adityas/Sun).
In Anushasana Parva, Bhishma instructs Yudhishthira on dharma and the fruits of various vows and austerities. Here he describes a specific long-term observance (restricted eating over a year, coupled with ethical restraints) and states its reward: reaching the vast, delightful worlds associated with the Adityas, especially Surya.
