In which Vibhīṣaṇa tells how Brahmā doomed devouring Kumbhakarṇa to sleep while Nīla bars the gates with boulders
Rāma asks Vibhīṣaṇa about the mountain like crowned giant — Vibhīṣaṇa names Kumbhakarṇa scourge of gods and demons — Kumbhakarṇa devoured thousands until Indra struck him with vajra — Kumbhakarṇa smote Indra with Airāvata tusk in return — Brahmā cursed him to sleep six months and wake one day — Rāvaṇa woke him in distress against Rāma — Nīla arrays monkeys with peaks trees rocks at Laṅkā gates
