मातङ्ग–शक्रसंवादः
Mataṅga–Śakra Dialogue on Tapas, Status, and Moral Qualities
भीष्म उवाच अत्राप्युदाहरन्तीममितिहासं पुरातनम् । शिलोज्छवृत्ते: संवादं सिद्धस्य च युधिष्ठिर
bhīṣma uvāca | atrāpy udāharantīmam itihāsaṁ purātanam | śilocchavṛtteḥ saṁvādaṁ siddhasya ca yudhiṣṭhira ||
毗湿摩说道：“优提施提罗啊！在此事上，人们也援引一则古老的先例。且听那旧闻——一位以拾取落谷为生（śiloccavṛtti）之人与一位成就者（悉地者，siddha）之间的对话，用以阐明此一法义。”
भीष्म उवाच
Educational Q&A
Bhishma introduces an ancient illustrative story to clarify dharma: ethical questions are best understood through precedents that highlight self-restraint, purity of livelihood, and the authority of realized wisdom (a siddha) in guiding conduct.
Bhishma tells Yudhishthira that, to explain the topic under discussion, he will recount an old itihasa—specifically a conversation between a man living by gleaning fallen grains (śilocchavṛtti) and a siddha—setting up the moral instruction that follows in subsequent verses.
