Along with contemporary haridasa saints such as Gopala Dasa, Helevankatte Giriamma, Jagannatha Dasa and Prasanna Venkata Dasa, he propagated the virtues of the philosophy of Madhwacharya across South India through devotional songs called "devaranama" written in the Kannada language.  An integral part of Kannada Vaishnava devotional literature, these compositions in praise of the Hindu god Vishnu are called "dasara padagalu" (compositions of the "dasas").  These compositions can be more specifically categorized as "keertanas", "suladis","ugabhogas", and simply "padas".  They were easy to sing to the accompaniment of a musical instrument and dealt with "bhakti" (devotion) and the virtues of a pious life.
