Rewa Prasad Dwivedi (22 August 1935 – 21 May 2021) was a Sanskrit scholar, poet, writer, teacher, and critic. His original works include poetry as epics and lyrics, plays, and prose. He wrote the new literature under the pseudonym "sanatana", meaning 'the eternal'. He is also known as 'Acharya' Dwivedi ('the scholar' or 'the expert' Dwivedi).

Dwivedi's scholarship includes work on literary principles including modern theories in Sanskrit poetics and dramaturgy and preserving (editing, compiling, indexing, and republishing) the works of all major Sanskrit scholars.^{[citation needed]}

Rewa Prasad Dwivedi was born in Nadner^[3] (22 August 1935);^[4]), on the banks of the Narmada river in Madhya Pradesh, to Pandit Narmada Prasad Dwivedi and Lakshmi Devi. He was orphaned when he was about eight years old. After completing basic education in Sanskrit in Madhya Pradesh, he traveled as a teenager to Varanasi to study Sanskrit at Banaras Hindu University.^[5] Despite poverty, he excelled in Sanskrit language and literature in both the traditional system at Faculty of Sanskrit Vidya Dharma Vijnan,^[6] and modern system at Faculty of Arts^[7] at Banaras Hindu University. His primary teacher and mentor was Pandit Mahadev Shastri.^{[citation needed]} Dwivedi obtained a Sahityacharya title and a M.A. degree in Sanskrit from Banaras Hindu University.^{[citation needed]} He received a PhD from Ravi Shankar University, Raipur,^[8] in 1965, and a D.Litt. from Jabalpur University in 1974.^[9]

Dwivedi's main area of work is in Sanskrit Sahitya (literature), but he was an expert in the Sanskrit language disciplines of Navya-nyaya (logic), Darshana (philosophy), and Vyakarana (grammar), as well as the scripts of Brahmi, Sarada and Nagari.^{[citation needed]}

He traveled to the US, Canada, and Europe to participate in other World Sanskrit Conferences as part of Government of India's delegation, American Oriental Society Meeting,^[12] and in personal capacity to conduct manuscript reviews at institutions such as Harvard University's Houghton Library.^[13]
