Bhāgavata-Māhātmya and the Complete Summary of the Śrīmad-Bhāgavatam
रामस्य कोशलेन्द्रस्य चरितं किल्बिषापहम् । निमेरङ्गपरित्यागो जनकानां च सम्भव: ॥ २४ ॥
rāmasya kośalendrasya caritaṁ kilbiṣāpaham nimer aṅga-parityāgo janakānāṁ ca sambhavaḥ
The Śrīmad-Bhāgavatam recounts the sin-destroying, sanctifying pastimes of Lord Śrī Rāmacandra, king of Kośala. It also tells how King Nimi gave up his body and mentions the appearance of the descendants of King Janaka.
This verse states that the life and deeds of Rāma, the lord of Kośala, are kīlbiṣāpaha—capable of removing sinful reactions—indicating the purifying potency of hearing and remembering Rāma-kathā.
Śukadeva Gosvāmī is listing major Bhagavatam narratives; Nimi’s departure is included as a noteworthy dynastic and dharmic episode connected with royal lineages and spiritual themes.
Regularly hearing and reciting the Lord’s sacred histories (especially Rāma’s) is presented as a means of inner purification, while reflecting on the impermanence of the body (as with Nimi) supports detachment and steady dharma.
