Indra’s Brahma-hatyā, Flight from Sin, and Purification by Aśvamedha
इदं महाख्यानमशेषपाप्मनांप्रक्षालनं तीर्थपदानुकीर्तनम् । भक्त्युच्छ्रयं भक्तजनानुवर्णनंमहेन्द्रमोक्षं विजयं मरुत्वत: ॥ २२ ॥ पठेयुराख्यानमिदं सदा बुधा:शृण्वन्त्यथो पर्वणि पर्वणीन्द्रियम् । धन्यं यशस्यं निखिलाघमोचनंरिपुञ्जयं स्वस्त्ययनं तथायुषम् ॥ २३ ॥
idaṁ mahākhyānam aśeṣa-pāpmanāṁ prakṣālanaṁ tīrthapadānukīrtanam bhakty-ucchrayaṁ bhakta-janānuvarṇanaṁ mahendra-mokṣaṁ vijayaṁ marutvataḥ
In this great narration the Supreme Lord Nārāyaṇa is glorified, the excellence of bhakti is proclaimed, devotees such as Indra and Vṛtrāsura are described, and Indra’s release from sin and his victory over the demons are recounted. By understanding this episode one is cleansed of all sinful reactions; therefore the learned always read it and, on festival days, hear and recite it. This account is blessed, fame-giving, the remover of all sin, the conqueror of enemies, auspicious in every way, and an increaser of longevity.
Thus ends the Bhaktivedanta purports of the Sixth Canto, Thirteenth Chapter, of the Śrīmad-Bhāgavatam, entitled “King Indra Afflicted by Sinful Reaction.”
This verse says it cleanses all sins, increases devotion, brings auspiciousness and fame, grants victory over enemies, promotes well-being, and supports longevity.
Śukadeva Gosvāmī speaks this to Mahārāja Parīkṣit while concluding the glorification of the sacred narration and its spiritual results.
Set a steady routine of śravaṇa and pāṭha (hearing/reciting Bhagavatam), and on holy days prioritize attentive kīrtana and study to strengthen bhakti and purify habits.
