"Vaisampayana continued, 'Having heard these words of the monarch, Vidura said, 'O king, let thy understanding remain so without change for a hundred years!' Having said this Vidura returned to his own abode. Then, O monarch, there came unto Dhritarashtra, Duryodhana and the son of Radha, Karna. Addressing the monarch, they said, 'We cannot, O king, speak of any transgression in the presence of Vidura! We have now found thee alone, and will, therefore, say all we like! What is this that thou hast, O monarch, desired to do? Dost thou regard the prosperity of thy foes as if it were thy own, that thou hast been applauding the Pandavas, O foremost of men, in the presence of Vidura? O sinless one, thou actest not, O king, in the way thou shouldst! O father, we should now act every day in such a way as to weaken (the strength of) the Pandavas. The time hath come, O father, for us to take counsel together, so that the Pandavas may not swallow us all with our children and friends and relatives.'"
