ଭୀଷ୍ମ କହିଲେ—ହେ ଭରତବଂଶୀ ଯୁଧିଷ୍ଠିର! ତିନି ଦ୍ୱିଜବର୍ଣ୍ଣରେ ଜାତକର୍ମ ଆଦି ସମସ୍ତ ସଂସ୍କାର ବିଧିବଦ୍ଧ। ବ୍ରାହ୍ମଣ, କ୍ଷତ୍ରିୟ ଓ ବୈଶ୍ୟ—ଏ ତିନିଜଣଙ୍କ ସଂସ୍କାର ବେଦମନ୍ତ୍ର ଉଚ୍ଚାରଣ ସହିତ ହିଁ ବିଧିପୂର୍ବକ କରିବା ଉଚିତ।

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.
