Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 5
Sanskrit:
स चापि तदु ह पितृसन्निधावेवासध्रीचीनमिव स्म करोति छन्दांस्यध्यापयिष्यन्सह व्याहृतिभि: सप्रणवशिरस्त्रिपदीं सावित्रीं ग्रैष्मवासन्तिकान्मासानधीयानमप्यसमवेतरूपं ग्राहयामास ॥ ५ ॥
ITRANS:
sa cāpi tad u ha pitṛ-sannidhāv evāsadhrīcīnam iva sma karoti chandāṁsy adhyāpayiṣyan saha vyāhṛtibhiḥ sapraṇava-śiras tripadīṁ sāvitrīṁ graiṣma-vāsantikān māsān adhīyānam apy asamaveta-rūpaṁ grāhayām āsa.
Translation:
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.
