Yudhishthira had instructed his brothers most strictly that nothing should be done to cause the slightest pain to their uncle, who had lost all his sons. The brothers, with perhaps the exception of Bhima, followed this injunction faithfully. Dhritarashtra too conducted himself lovingly towards the Pandavas. He showed no ill will towards them even as they showed him no unkindness. The Pandavas behaved unexceptionably towards their old uncle. After a time, however, Bhima began on occasions to give cause for offence. He would sometimes, in impatience, countermand the old man's instructions. He would let fall in Dhritarashtra's hearing words like "Those perverse cousins of ours have themselves to thank for their destruction." It was not possible for Bhima to forget or forgive Duryodhana, Karna or Duhsasana. Gandhari felt intensely grieved when she noticed that Bhima uttered words, which pained Dhritarashtra. She was, however, a noble and enlightened soul. Whenever she felt pained at what Bhima said, she would look at Kunti and find peace. For Kunti was a veritable embodiment of dharma and inspired forbearance. Fifteen years passed in this manner.
