CC Antya 6.137
jahau yuvaiva mala-vad
yaḥ — who (Bharata Mahārāja); dustyajān — difficult to give up; dāra-sutān — wife and children; suhṛt — friends; rājyam — kingdom; hṛdi-spṛśaḥ — dear to the core of the heart; jahau — gave up; yuvā — youth; eva — at that time; mala-vat — like stool; uttama-śloka-lālasaḥ — being captivated by the transcendental qualities, pastimes and association of the Supreme Personality of Godhead.
“ ‘Lord Kṛṣṇa, the Supreme Personality of Godhead, is offered sublime, poetic prayers by those trying to attain His favor. Thus He is known as Uttamaśloka. Being very eager to gain the association of Lord Kṛṣṇa, King Bharata, although in the prime of youth, gave up his very attractive wife, affectionate children, most beloved friends and opulent kingdom, exactly as one gives up stool after excreting it.’ ”
This verse is from Śrīmad-Bhāgavatam (5.14.43).
