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
श्रीमद्भागवते कोशलेन्द्रस्य श्रीरामस्य पावनं चरितं किल्बिषापहं वर्ण्यते; तथा निमेः देहपरित्यागः, जनकवंशस्य च सम्भवोऽपि कथ्यते।
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.
