धृतराष्ट्रः शोकमोहाभितप्तः ‘तरति शोकमात्मवित्’ इति वेदान्तवादमुपश्रुत्य ब्रह्मविद्यया विना शोकापनयनमशक्यं मन्वानः ‘अनुक्तं यदि ते किंचिद्वाचा विदुर विद्यते ।तन्मे शुश्रूषवे ब्रूहि विचित्राणीह भाषसे’ इति विदुरायोक्तवान् ।स च श्रुतवाक्योऽपि परमकारुणिकः सर्वज्ञः सन् ब्रह्मविद्यां विशिष्टाधिकारिविषयां मन्वानः ‘शूद्रयोनावहं जातो नातोऽन्यद्वक्तुमुत्सहे’ इति शूद्रयोनिजत्वादौपनिषदब्रह्मात्म-
In plain words
King Dhritarashtra, scorched by grief and confusion, heard the Upanishadic declaration that the knower of the Self transcends all sorrow. Knowing that without this knowledge of Brahman his grief could never be removed, he turned to Vidura and said, 'Vidura, if you know any unspoken truth, please share it with an eager listener like me; you speak of wondrous things.' Though deeply compassionate and wise, Vidura considered the supreme science of Brahman to be meant for a specially qualified seeker, and replied, 'I was born from a śūdra womb, and therefore I am not bold enough to speak further on this.'
Close to the Sanskrit
Dhritarashtra, scorched by grief and delusion, having heard the Vedanta statement 'The knower of the Self crosses over grief', considering the removal of grief impossible without knowledge of Brahman, said to Vidura: 'O Vidura, if any unspoken truth exists with you by speech, tell it to me who am desirous of hearing; you discourse on wondrous things here.' And he, though omniscient and extremely compassionate, having heard the words, considering knowledge of Brahman to be a subject pertaining to a qualified recipient, said: 'I am born in a śūdra womb, therefore I do not have the heart to speak anything else.'
