Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
जातकर्मादिका: सर्वास्त्रिषु वर्णेषु भारत । ब्र्मक्षत्रे हि मन्त्रोक्ता वैश्यस्य च युधिष्ठिर
jātakarmādikāḥ sarvāstrīṣu varṇeṣu bhārata | brahmakṣatre hi mantroktā vaiśyasya ca yudhiṣṭhira ||
ビーシュマは言った。「バーラタの末裔、ユディシュティラよ。三つの『再生者（ドヴィジャ）』の身分には、出生儀礼（ジャータカルマ）をはじめとする一切のサンスカーラが定められている。バラモンとクシャトリヤ、そしてヴァイシャもまた、これらの儀礼はヴェーダのマントラを誦して行うべきである。」

Educational Q&A
Bhishma teaches that the classical life-cycle sacraments (saṃskāras), starting with jātakarma, are prescribed for the three twice-born varṇas—Brahmin, Kshatriya, and Vaishya—and that these rites should be performed with Vedic mantra-recitation, emphasizing ritual propriety as part of dharma.
In the Anushasana Parva’s instruction on dharma, Bhishma continues advising King Yudhishthira about duties and norms. Here he specifies who is entitled/obligated to perform the saṃskāras and how—namely, with mantras—for the three varṇas he lists.
