Jinaratnasuri (Jina·ratna·suri; Hindi: जिनरत्नसूरी was a Śvetāmbara Jain scholar and a monk of Kharatara Gaccha, who composed Līlāvatīsāra.
Jinaratnasuri in his introductory verses to Līlāvatīsāra describes how his interest in Jineshvarasuri's poem was stimulated by his own teacher.
Jinaratnasuri displays his mastery of Sanskrit poetics by interspersing complex lyric metres throughout his poem.
Not only does Jinaratnasuri employ rare works and unusual grammatical forms drawn from the Sanskrit lexicons and grammars, but he also incorporates into his poem words taken from contemporary spoken vernaculars.
Jinaratnasuri's language in the narrative portions of the poem is fast moving and direct, but it is far more ornate in his descriptions of cities, mountains, desert wilderness, battles, festivals, and other topics with which a Sanskrit epic should be embellished.
