Shloka 29
उपवासफलात्मकविधिः — Upavāsa as Yajña-Equivalent Merit
Angiras Teaching
तथैवाश्वयुजं मासमेकभक्तेन य: क्षिपेत् मृजावान् वाहनाद्यश्व बहुपुत्रश्न जायते,जो आश्विन मासको एक समय भोजन करके बिताता है, वह पवित्र, नाना प्रकारके वाहनोंसे सम्पन्न तथा अनेक पुत्रोंसे युक्त होता है
tathaivāśvayujaṁ māsam ekabhaktena yaḥ kṣipet | mṛjāvān vāhanādyaiś ca bahuputraś ca jāyate ||
安祇罗说：同样地，若有人在阿湿婆瑜阇月（即阿湿温月）守持一日一食之律，其行止得以清净，福报显现为种种车乘与安乐资具，并蒙赐多子之庆，得众多儿子。
अंगियरा उवाच
Educational Q&A
The verse teaches that disciplined restraint—specifically the vow of eating only once daily during the month of Āśvayuja—purifies a person and is said to generate merit that manifests as prosperity (comforts like conveyances) and familial flourishing (many sons).
In Anuśāsana Parva’s instruction on vows and their fruits, the sage Aṅgirā continues listing month-based observances; here he states the result of observing ekabhakta (single daily meal) throughout Āśvayuja.
