शार्दूलचरवृत्तान्तः (Saardula’s Spy-Report on Rama’s Camp and the Vanara Host)
नास्तिरामस्यसदृशोविक्रमेभुविकश्चन ।विराधोनिहतोयेनकबन्धश्चान्तकोपमः ।।6.30.29।।
nāsti rāmasya sadṛśo vikrame bhuvi kaścana | virādho nihato yena kabandhaścāntakopamaḥ ||
On earth there is none equal to Rāma in valor; it was he who slew Virādha and Kabandha, who was like Death itself.
"Viradha and even Kabhanda who was like the Lord of death were killed by Rama. Perhaps there is none equal to Rama in valour in this world."
Shuka, the spy of Ravana, is describing Rama's unmatched valor to his master.
The killing of the formidable demons Viradha and Kabandha (who resembled Death) are cited as proof.
