Mbh 12.52.2

"'Bhishma said, "O master of all the worlds, O mighty-armed one, O Siva, O Narayana, O thou of unfading glory, hearing the words spoken by thee I have been filled with joy. But what words (of instruction), O master of speech, can I say in thy presence, when especially in all the subjects of speech have been dealt with in thy speech?[157] Whatever in either world should be done or is done, proceeds from thy intelligent self, O god! That person who is competent to discourse on the subject of heaven in the presence of the chief of the gods himself is competent to discourse on the interpretation of morality and pleasure and profit and salvation in thy presence. My mind, O slayer of Madhu, is exceedingly agitated by the pain of arrow-wounds. My limbs are weak. My understanding is not clear. I am so afflicted, O Govinda, by these shafts resembling poison or fire that I have not power to utter anything. My strength is abandoning me. My life-breaths are hastening to leave me. The very vitals of my body are burning. My understanding is clouded. From weakness my utterance is becoming indistinct. How then can I venture to speak? O enhancer of (the glory of) Dasarha's race, be gratified with me. O mighty-armed one, I will not say anything. Pardon me (for my unwillingness). The very master of speech (Vrihaspati), in speaking in thy presence, will be overcome by hesitation. I cannot any longer distinguish the points of the compass, nor the sky from the earth! Through thy energy, O slayer of Madhu, I am only barely alive. Do thou, therefore, thyself speak for the good of king Yudhishthira the just, for thou art the ordainer of all the ordinances. How, O Krishna, when thou, the eternal creator of the universe, art present, can one like me speak (on such subjects) like a disciple in the presence of the preceptor?"
