Saṃhāra-krama (The Sequence of Cosmic Dissolution) — Yājñavalkya’s Discourse
पक्षान् मासानृतूंश्चैतान् संवत्सरानहस्तथा । अप: पीत्वा पयोमिश्रा योगी बलमवाप्नुयात्
pakṣān māsān ṛtūṁś caitān saṁvatsarān ahas tathā | apaḥ pītvā payomiśrā yogī balam avāpnuyāt ||
भीष्म ने कहा—पक्ष, मास, ऋतु और वर्ष—इन क्रमशः बढ़ते अंतरालों के अनुसार नियत समय पर दूध-मिश्रित जल का पान करके योगी धीरे-धीरे बल को प्राप्त करता है।
भीष्म उवाच
Progressive restraint in consumption—extending intervals from daily to fortnightly, monthly, seasonal, and yearly—cultivates tapas and steadiness; through such disciplined practice the yogin attains strength (bala) and yogic capacity.
In Śānti Parva, Bhīṣma instructs on dharma and spiritual disciplines; here he describes an ascetic regimen involving drinking water mixed with milk at increasingly spaced intervals as an example of controlled austerity leading to inner power.
