युक्तियुक्तं वचो ग्राह्यं न ग्राह्यं गुरुगौरवात् ।
सर्वशास्त्ररहस्यं तद्याज्ञवल्क्येन भाषितम् ॥
yukti-yuktaṁ vaco grāhyaṁ na grāhyaṁ guru-gauravāt |
sarva-śāstra-rahasyaṁ tad yājñavalkyena bhāṣitam ||
(Yājñavalkya-śikṣā: 232)
“A statement that is endowed with reason is to be accepted and not to be accepted [just] because of reverence for the guru [alt., just because of the venerability of the guru, who spoke it]. This secret of all the śāstras has been stated by Yājñavalkya.”
