The brāhmaṇa father’s mind was always filled with affection for his son, Jaḍa Bharata [Bharata Mahārāja]. Therefore he was always attached to Jaḍa Bharata. Because Jaḍa Bharata was unfit to enter the gṛhastha-āśrama, he simply executed the purificatory process up to the end of the brahmacarya-āśrama. Although Jaḍa Bharata was unwilling to accept his father’s instructions, the brāhmaṇa nonetheless instructed him in how to keep clean and how to wash, thinking that the son should be taught by the father.

तस्यापि ह वा आत्मजस्य विप्रः पुत्रस्नेहानुबद्धमना आ समावर्तनात्संस्कारान् यथोपदेशं विदधान उपनीतस्य च पुनः शौचाचमनादीन् कर्मनियमा- ननभिप्रेतानपि समशिक्षयदनुशिष्टेन हि भाव्यं पितुः पुत्रेणेति
