Shloka 18
अव्यक्त-प्रबोधः (Awakening to the Unmanifest): The 25th and 26th Principles and Eligibility for Brahma-vidyā
कर्मतो<न्यानि गोत्राणि समुत्पन्नानि पार्थिव । नामधेयानि तपसा तानि च ग्रहणं सताम्
karmato 'nyāni gotrāṇi samutpannāni pārthiva | nāmadheyāni tapasā tāni ca grahaṇaṃ satām ||
パラーシャラは言った。「王よ、ほかのゴートラ（氏族）は、人々の行為と役目に応じて後に生じた。その名号すら、創始の聖仙たちの苦行によって定められ、善き人々の間で受け入れられ敬われるようになった。」
पराशर उवाच
Educational Q&A
The verse teaches that social lineages and their recognized names are not merely arbitrary; they are understood to arise in relation to karma (deeds/roles) and gain legitimacy through the tapas (spiritual merit) of the founding sages, hence being honored by the righteous.
Parāśara is instructing a king in the Śānti Parva on the origin and social recognition of gotras, explaining how later gotras emerged and why their names became accepted among respectable people.
