Angiras Teaching
पज्चम्यां वापि षष्ठ्यां च पौर्णमास्यां च भारत । उपोष्य एकभक्तेन नियतात्मा जितेन्द्रिय:
pañcamyāṃ vāpi ṣaṣṭhyāṃ ca paurṇamāsyāṃ ca bhārata | upoṣya ekabhaktena niyatātmā jitendriyaḥ ||
安吉罗说：“噢，婆罗多啊，若有人调伏其心、制胜诸根，于初五、初六以及满月之日持斋——只进一餐（另一时则禁食）——便能性情宽恕，仪容端美，且博学多闻。如此智者，决不陷于无嗣或贫困。”

Educational Q&A
Regular, disciplined fasting on specific lunar days—paired with restraint of mind and senses and the ekabhakta practice (one meal)—is presented as a dharmic austerity that cultivates virtues (especially forgiveness) and supports well-being, learning, and stability in household life.
In Anuśāsana Parva’s instruction on dharma and observances, the sage Aṅgiras addresses “Bhārata” and recommends a vrata: fasting on pañcamī, ṣaṣṭhī, and paurṇamāsī with self-control, describing the ethical and worldly fruits attributed to this practice.
