During his childhood, he was influenced by the writings of Gorur Ramaswamy Iyengar.

 Bhyrappa completed his primary education in Channarayapatna taluk before moving to Mysore where he completed the rest of his education. In his autobiography, Bhitti (Wall) he wrote that he took a break during his high school education. Bhyrappa impulsively quit school, following his cousin's advice and wandered for a year with him. His sojourn led him to Mumbai, where he worked as a railway porter. In Mumbai he met a group of sadhus and joined them to seek spiritual solace.

Vamshavruksha has received the Kannada Sahitya Academy Award in 1966 and Daatu (Crossing Over) received both the Kannada and the Kendra Sahitya Academy awards in 1975. Parva, the most critically acclaimed of all his novels narrates the social structure, values and mortality in the epic of Mahabharata very effectively. Bhyrappa reconstructs the Mahabharatha from sociological and anthropological angle, through metaphors in this novel. Tantu, a Kannada novel was published in 1993. Tantu ( meaning 'cord' or 'links') explored relations or links between human emotions. It was translated into English in the year 2010 by Niyogi Books.

 Bhyrappa was the center of several controversies because of his themes and positions on sensitive issues. Some of his prominent novels (such as Vamshavruksha, Tabbaliyu Neenaade Magane, Parva, and Saartha) have strong roots in ancient Indian philosophical tradition, thus inviting severe criticism from Navya writers and from others. Bhyrappa supported N. R. Narayana Murthy when he was criticized by the media and the public regarding the controversy over playing an instrumental version of the national anthem at an important occasion. He also backed N. R. Narayana Murthy regarding the Kaveri issue saying riots and protests are not going to solve the problem. Bhyrappa had a debate with Girish Karnad in the publication Vijaya Karnataka regarding the religious tolerance of 18th century Mysore ruler Tippu Sultan.[citation needed] In Bhyrappa's novel Aavarana, he accuses Tippu Sultan of being a religious fanatic who could not stand Hindus in his court. Bhyrappa has attempted to substantiate his argument based on several historical sources written in India. For example, Bhyrappa has pointed to the usage of the Arabic patronymic bin (used in personal names to mean "son of") in governmental records, which Bhyrappa claims has continued even into modern times in Karnataka. According to Bhyrappa, this practice, initiated under the rule of Tippu Sultan, was one of several methods used to enforce Islamic rule on Hindus.[citation needed] The book discusses other methods used by Tippu Sultan to convert Hindus to Islam. This view was criticized by Girish Karnad, who has portrayed Tippu Sultan as a secular ruler in his plays. Bhyrappa has countered that Karnad portrays Tippu Sultan inaccurately in his plays.
 U.R. Ananthamurthy was a prominent critic of Bhyrappa's novels. Bhyrappa has documented his debate with Ananthamurthy in Bhitti, as well as in a few essays in his book Naaneke Bareyuttene. Bhyrappa's more recent novel Aavarana brings out historical information about what Islamic rule did to ancient Indian social and cultural life. This has stirred a major controversy. There have been accusations leveled at Bhyrappa of being a Hindu fundamentalist who wants to divide society on the basis of history, an allegation which Bhyrappa anticipated and tried to refute by referring to notable sources. Ananthamurthy criticized Bhyrappa and his works, calling Aavarana "dangerous". Ananthamurthy accused Bhyrappa of being more of a debater than a storyteller. "He doesn't know what Hindu religion stands for" and "does not know how to write novels". However Bhyrappa claims that the novel was result of his search for truth and there was no ulterior motive behind the novel. He urged critics to study the reference books mentioned in the novel before arriving at any conclusion about it.
 His short story "Avva" was published in the Kasturi magazine and it's considered as his maiden short story.
