मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
दिवसे सप्तदशमे य: प्राप्ते प्राशते हवि:
divase saptadaśame yaḥ prāpte prāśate haviḥ | yo manuṣyaḥ dvādaśa māsān pratidinam agnihotraṃ kurvan ṣoḍaśa-dināni upavāsya saptadaśe dine kevalaṃ havyāśyaṃ bhojanaṃ karoti, sa varuṇa-indra-rudra-marut-śukrācārya-brahma-lokeṣu gacchati; teṣu lokeṣu devakanyā āsanaṃ dattvā tasya pūjāṃ kurvanti ||
毗湿摩说：至第十七日之时，若有人十二个月日日奉行阿耆尼火供（Agnihotra），继而斋戒十六日，并于第十七日唯食以供品为本的简朴“哈维施亚”(haviṣya)之餐，便能到达尊胜天界——伐楼那、因陀罗、鲁陀罗、诸摩鲁特、乌沙那（即舒克罗阿阇梨）以及梵天之界。在那些世界里，天女为他设座，恭敬供养礼拜。

Educational Q&A
Sustained ritual duty (daily Agnihotra) combined with disciplined austerity (sixteen-day fast and a simple haviṣya meal on the seventeenth day) is presented as a dharmic practice that yields exalted spiritual merit, culminating in attainment of divine realms and honor among celestial beings.
Bhishma is instructing on religious observances and their fruits. He describes a specific vow-like regimen—one year of daily Agnihotra, followed by sixteen days of fasting and a haviṣya meal on day seventeen—and states the heavenly destinations and honors that accrue to the practitioner.
