Gṛhastha-vṛtti and Niyama: Models of Householder Livelihood and Discipline (गृहस्थवृत्ति-नियमाः)
एतत् प्रज्ञामयैर्धीरा निस्तरन्ति मनीषिण: । प्लवैरप्लववन्तो हि कि करिष्यन्त्यचेतस:
etat prajñāmayair dhīrā nistaranti manīṣiṇaḥ | plavair aplavavanto hi kiṁ kariṣyant acetasaḥ ||
因此，坚忍而明辨的智者，凭借由智慧铸成的舟筏，得以渡过（时间之险流与世间之危难）。而那些没有此等舟筏的人——缺乏辨识之人——又能做得了什么呢？
