Adi Shankara

Adi Shankara (born 788 BCE, died 820 BCE) was an Indian philosopher and theologian who is credited with refining the Hindu doctrine of Advaita Vedanta. He also helped differentiate the philosophies of Buddhism from Hinduism, chiefly through his affirmation that in Hinduism, “Atman” (the soul or self) exists, whereas in Buddhism there is no concept of soul or self.
