Adi Shankara

Adi Shankara, also known as Adi Shankaracharya, was an influential Indian philosopher and theologian who lived in the early 8th century CE (approximately 788–820 CE). He is best known for consolidating the doctrine of Advaita Vedanta, a non-dualistic school of thought in Hindu philosophy that emphasizes the idea of a singular reality (Brahman) and the view that the individual self (Atman) is fundamentally the same as this ultimate reality.
