śrīmān reca-mahīpatiḥ sucarito yasyānujanmā sphuṭaṃ
prāpto vīra-guru-prathāṃ pṛthutarāṃ vīrasya mudrākarīm |
labdhvā labdha-kaṭhāri-rāya-virudaṃ rāhuttarāyāṅkitaṃ
putraṃ nāgayanāyakaṃ vasumatī-vīraika-cūḍāmaṇim ||

His younger brother, the illustrious King Reca of noble conduct, manifestly / achieved immense renown as a master of heroes, affixing the seal of valour, / having obtained a son, Nāgaya Nāyaka, the sole crest-jewel among heroes of the earth, / who bore the title Kaṭhārīrāya and was marked as Rāhuttarāya.
