Shloka 15
Kṣātra-dharma as the Public Foundation of Dharma (क्षात्रधर्म-प्रशंसा)
कृतकृत्यो वयो5तीतो राज्ञ: कृतपरिश्रम: । वैश्यो गच्छेदनुज्ञातो नृपेणाश्रमसंश्रयम्
kṛtakṛtyo vayotīto rājñaḥ kṛtaparishramaḥ | vaiśyo gacched anu-jñāto nṛpeṇāśramasaṃśrayam ||
毗湿摩说道：“当一位吠舍尽其本分，年岁既高，已完成其阶分所要求的一切劳作之时，他应当——在获得国王许可之后——退出尘务，归依一处阿湿罗摩，采取与其由家居责任转入清修相称的林栖者（vānaprastha）之行。”

Educational Q&A
After properly completing one’s prescribed social duties (varṇa-dharma) and reaching old age, one should transition toward a disciplined, renunciatory life (āśrama), doing so in an orderly way that respects social governance—here, by seeking the king’s permission.
In Bhishma’s instruction on dharma in the Śānti Parva, he outlines a normative life-course for a Vaiśya: having fulfilled household and occupational responsibilities, the person may withdraw from active worldly engagement and take up an āśrama-oriented life, with royal authorization.
