Jaḍa Bharata behaved before his father like a fool, despite his father’s adequately instructing him in Vedic knowledge. He behaved in that way so that his father would know that he was unfit for instruction and would abandon the attempt to instruct him further. He would behave in a completely opposite way. Although instructed to wash his hands after evacuating, he would wash them before. Nonetheless, his father wanted to give him Vedic instructions during the spring and summer. He tried to teach him the Gāyatrī mantra along with oṁkāra and vyāhṛti, but after four months his father still was not successful in instructing him.
