रावणम् Ravana, कृद्धम् became angry, आज्ञाय: having realized, महाबलः one of extraordinary strength, महापार्श्वः Mahaparsva, मुहूर्तम् for a short time, अनुसञ्चिन्त्य: thinking of pleasing, प्राञ्जलिः greeting with folded palms, वाक्यम् these words, अब्रवीत् spoke.

Having realized that Ravana has become angry, Mahaparsva of extraordinary strength, thinking of pleasing him for a while greeting him with folded palms, spoke. Mahaparsva advises Ravana to force Sita, and Ravana expresses his inability to do so because of the curse pronounced by Brahma.
