Shankaracharya
(788 CE - 820 CE) Also known as Adi Shankara. Although he only lived for thirty-two years, Shankara established a philosophical view that showed the unity of the various religions of India, especially Buddhism and Hinduism.
"Shankara was a ray of the primitive light; he was a flame. Shankara joined the Buddhist doctrine with the Advaita philosophy." - Samael Aun Weor, Igneous Rose
