ज्येष्ठ-कनिष्ठ-धर्मः — Duties of Elders and Juniors
Anuśāsana-parva 108
न चैकेन परिव्रज्यं न गन्तव्यं तथा निशि । अनागतायां संध्यायां पश्चिमायां गृहे वसेत्
na caikena parivrajyaṁ na gantavyaṁ tathā niśi | anāgatāyāṁ sandhyāyāṁ paścimāyāṁ gṛhe vaset ||
毗湿摩说道：不可独自游荡，也不可在夜间行旅。暮色未至之前——尤其当西方夕阳将沉、黄昏逼近之时——当安住家中。此教诲在于谨慎持身：避开独行与夜行，务必在薄暮之前归家，以保安全与礼法。

Educational Q&A
Practice prudent conduct: do not roam alone, avoid traveling at night, and return home before evening twilight. It frames safety and propriety as part of dharma (right conduct).
In the Anushasana Parva, Bhishma is instructing Yudhishthira on dharma and proper behavior. Here he gives a practical rule of conduct concerning travel and timing—counsel meant to prevent danger and uphold disciplined living.
