Vidyaranya was a kingmaker and priest to Harihara Raya I and Bukkai Raya I, the founders of the Vijayanagar Empire. He was the mentor and guide to three generations of kings who ruled over the Vijayanagar Empire. Vidyaranya has authored `Sarvadarsanasangraha`, which is regarded as an important text in the `Advaita Vedanta`.
`Vidya-sankara` or `Vidyatirtha`, who was the head of the Sankaracharya Mutt of Sringeri, was the teacher of Vidyaranya. Vidyaranya was an `Advaitin` and helped Harihara and Bukka in the task of reviving the Vedic religion.
Vidyaranya wrote the `Panchadashi`, a popular and comprehensive manual of Advaita Vedanta in Sanskrit. The king of Vijayanagara Harihara I built a temple at Hampi in honour of Vidyaranya
