प्रतिग्रहभेदः — The Distinction between Giving and Accepting
Vṛṣādarbhī–Saptarṣi Dialogue
सो<यं स्वयम्भुविहितो धर्म: संकल्पितस्त्वया । ऋते स्वयम्भुव: कोडन्य: श्राद्धेयं विधिमाहरेत्
so ’yaṁ svayambhuvihito dharmaḥ saṅkalpitas tvayā | ṛte svayambhuvaḥ ko ’nyaḥ śrāddheyaṁ vidhim āharet ||
ビーシュマは言った。「汝が行じるこのダルマは、もとより自生者スヴァヤンブー（梵天ブラフマー）が定めたものだ。スヴァヤンブーをおいて、誰がシュラーダ（śrāddha）に供すべきものの正しい作法を説き得ようか。ゆえに汝の行は、ブラフマーの立てた原初の規範に従うのである。」

The verse grounds śrāddha and related dharma in primordial authority: the correct ritual procedure is not arbitrary but traced to Svayambhu (Brahmā), implying that faithful observance aligns one with an original, universally sanctioned order.
Bhishma, instructing on dharma in the Anushasana Parva, affirms that the listener’s performance follows the ancient rule established by Brahmā and rhetorically emphasizes that no one else could authoritatively prescribe the śrāddha-vidhi.
