Nijaguna Shivayogi (15th century) was an Indian poet and a prolific writer in the Kannada language. He lived in the 15th century. He was a follower of the Veerashaiva faith (devotee of the Hindu god Shiva), which he attempted to reconcile with the Advaita Hinduism of Adi Shankaracharya.[1] Tradition has it that Shivayogi was a petty chieftain of Kollegal taluk in modern Mysore district of Karnataka state, India.[1] Considered a visionary of his time, his Vivekachintamani, written in encyclopaedic proportions and in prose style, and the Kaivalya Paddhati, a musical treatise consisting of songs are considered his most enduring works.[1][2]
