yukti-yuktaṁ vaco grāhyaṁ na grāhyaṁ guru-gauravāt
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.”
