yaḥ pañca-varṣo guru-dāra-vāk-śarair bhinnena yāto hṛdayena dūyatā /
vanaṃ mad-ādeśa-karo 'jitaṃ prabhuṃ jigāya tad-bhakta-guṇaiḥ parājitam //

42. A child of five years of age, with a painful heart wounded with the arrow-like words of his step-mother (lit. another wife of his father), he betook himself to the forest and there doing what I told him, he has attained the grace of the unconquered Lord who is prevailed upon (only) by the excellent qualities of His votaries.
