मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
सदा द्वादशमासान् वै ब्रह्मलोकमवाप्नुयात् । जो बारह महीनोंतक प्रत्येक मास व्यतीत होनेपर तीसवें दिन एक बार भोजन करता और सदा शान्तभावसे रहता है, वह ब्रह्मलोकको प्राप्त होता है
sadā dvādaśa-māsān vai brahma-lokam avāpnuyāt |
毗湿摩说：若有人终岁十二月持守严谨之行——每月仅于第三十日进食一次，且恒住安静之心——便能得至梵天界（Brahmaloka）。此教旨称赞长久自制与内在宁定，为通向崇高灵界之正法之道。

Educational Q&A
Sustained austerity (regulated eating) combined with steady inner calm is presented as a powerful dharmic discipline whose fruit is attainment of a higher spiritual realm (Brahmaloka).
In Bhishma’s instruction on dharma and religious observances, he describes the merit of a year-long vow: eating only once every month on the thirtieth day while remaining peaceful in mind, culminating in the reward of Brahmaloka.
