Shloka 25
अव्यक्त–प्रकृति–इन्द्रियविचारः
The Unmanifest, Prakṛtis, and the Sense-Complex
मृण्मये भाजने पक्वे यथा वै न श्यति द्रव: । तथा शरीरं तपसा तप्तं विषयमश्लुते
mṛṇmaye bhājane pakve yathā vai na śyati dravaḥ | tathā śarīraṃ tapasā taptaṃ viṣayam aśnute |
波罗娑罗说：“譬如液体置于烧制坚实的陶器之中，既不渗漏亦不败坏；同样，微细之身经由苦行之‘火’锻炼而坚固成器，便能不散不损地领受并体验高界诸境（乃至梵天界）。”
पराशर उवाच
Educational Q&A
Tapas (disciplined austerity) ‘hardens’ and stabilizes the inner constitution—like firing a clay pot—so that one can bear and properly undergo experiences (even refined, higher-world enjoyments) without leakage, dissipation, or moral/spiritual spoilage.
Parāśara is instructing through an analogy: as a well-fired earthen vessel securely holds liquid, so a body refined by austerity becomes capable and steady, able to attain and experience objects of enjoyment in higher realms without being undone by them.
