Kumāradāsa is the author of a Sanskrit Mahākāvya called the Jānakī-haraṇa or Jānakī's abduction.
Sita was abducted by Ravana when she along with the Rama, exiled from his kingdom, and Lakshmana was living in a forest which incident is taken from Ramayana ('Rama's Journey'), the great Hindu epic written by Valmiki.
The Sinhalese translation of his work, Jānakī-haraṇa, gave credence to the belief that Kumāradāsa was King Kumāradhātusena (513-522 A.D.) of Sri Lanka but most scholars do not make any such identification even though the poet at the end of his poem says that his father, Mānita, a commander of the rearguard of the Sinhalese King Kumāramaṇi, died in battle on the day he was born and that his maternal uncles, Megha and Agrabodhi, brought him up.
[2] In his "Survey of Sanskrit Literature", about Kumāradāsa and Jānakī-haraṇa (20 Cantos), which poem the poet is believed to have written during his stay in Kanchipuram where he lived,[3] C. Kunhan Raja Ph.D. says: A verse in the Subhāṣita-ratna-kośa refers to Kumāradāsa's Jānakī-haraṇa:
jānakī-haraṇaṃ kartuṃ raghuvaṃśe puraḥsthite / kaviḥ kumāradāso vā rāvaṇo vā yadi kṣamaḥ // To have produced an Abduction of Sita, When the Dynasty of Raghu was present before him — One must have been Kumāradāsa or else been Rāvaṇa.
