हुताशनज्वालसमावृता engulfed in the flames spread by the Firegod, हतप्रवीराः with its heroes dead, परिवृत्तयोधा with the retreating troops, हनूमतः Hanuman's, क्रोधबलाभिभूता by Hanuman's power of anger, सा लङ्का that Lanka, शापोपहतेव as if cursed, बभूव became.

With the Fire god spreading flames all over, heroes dead, retreating troops shattered by Hanuman's anger, Lanka appeared as though it was cursed.
