 He came from a family of famous poet-writers.Although five of Keshiraja's writings are not traceable, his most enduring work on Kannada grammar, "Shabdamanidarpana" ("Mirror of Word Jewels", 1260), is available and testifies to his scholarly acumen and literary taste.True to his wish that his writing on grammar should "last as long as the sun, the moon, the oceans and the Meru mountain lasted", "Shabdamanidarpana" is popular even today and is considered a standard authority on old Kannada grammar.
