यत्तु पक्षे गते भुडक्ते एकभक्तं जितेन्द्रिय: । सदा द्वादशमासांस्तु जुह्दानो जातवेदसम्,जो जितेन्द्रिय पुरुष बारह महीनोंतक प्रति पंद्रहवें दिन एक बार खाता और प्रतिदिन अग्निहोत्र करता है, वह एक हजार राजसूय यज्ञका सर्वोत्तम फल पाता है और हंस तथा मोरोंसे सेवित दिव्य विमानपर आरूढ़ होता है
yat tu pakṣe gate bhuñkte ekabhaktaṁ jitendriyaḥ | sadā dvādaśa-māsāṁs tu juhvāno jātavedasam ||
Bhishma said: But the self-controlled man who, after the fortnight has passed, eats only a single meal on the appointed day, and who for twelve months continually offers oblations into the sacred fire (Agni) each day, attains the highest merit—equal to that of a thousand Rājasūya sacrifices—and is borne aloft in a divine aerial car attended by swans and peacocks.
भीष्म उवाच
Disciplined restraint (jitendriyatā) combined with steady sacred duty (daily fire-offering) is presented as a powerful form of dharma, yielding merit comparable to grand royal sacrifices—showing that inner discipline and consistent practice can rival costly public rites.
Bhīṣma is describing a specific observance: eating only once at the end of each fortnight while maintaining daily offerings to Agni for a full year. He then states the exalted reward—equivalent to a thousand Rājasūyas and ascent in a divine vimāna attended by swans and peacocks.
