 Vachana poetry , developed in reaction to the rigid caste @-@ based Hindu society , attained its peak in popularity among the under @-@ privileged during the 12th century . Though these poems did not employ any regular metre or rhyme scheme , they are known to have originated from the earlier tripadi <unk> form . The <unk> , who wrote this poetry , had risen to influential positions by the Vijayanagara period ( 14th century ) . Court ministers and nobility belonging to the faith , such as <unk> <unk> and <unk> , not only wrote literature but also patronised talented writers and poets . Veerashaiva <unk> of the 15th and 16th centuries began to collect Shaiva writings and vachana poems , originally written on palm leaf manuscripts . Because of the cryptic nature of the poems , the <unk> added commentaries to them , thereby providing their hidden meaning and esoteric significance . An interesting aspect of this <unk> work was the translation of the Shaiva canon into Sanskrit , bringing it into the sphere of the Sanskritic ( <unk> or mainstream as opposed to <unk> or folk ) cultural order .
