Chapter 51: Jaṭāyu Fights with Rāvaṇa
Text 3.51.36
स तथा गृध्रराजेन क्लिश्यमानो मुहुर्मुहुः।
अमर्षस्फुरितोष्ठः सन्प्राकम्पत स रावणः।।
sa tathā gṛdhra-rājena kliśyamāno muhur muhuḥ
amarṣa-sphuritoṣṭhaḥ san prākampata sa rāvaṇaḥ
saḥ1 tathā = thus; gṛdhra-rājena = by the king of vultures; kliśyamānaḥ = when was being troubled; muhuḥ muhuḥ = repeatedly; amarṣa-sphurita-oṣṭhaḥ san = his lips trembled with rage; prākampata = then swirled around; saḥ = and he; rāvaṇaḥ = Rāvaṇa.
When Rāvaṇa was thus repeatedly troubled by the king of vultures, his lips trembled with rage and he [then] swirled around.1
Rāvaṇa swirled around to attack [Jaṭāyu].
