The absence of contemporary mentions about Sri Sankara Bhagavatpadacharya in the Stone and Copper plate Inscriptions, Sacred Tamil Hymns and Literary sources belonging to the 8th-9th century C.E period along with mismatch with the names of the Ruling Kings found in Sri Sankaracharya’s Traditional biographies, suggests that He lived and flourished during the 6th century B.C.E. rather than the proposed 8th century C.E.
The historical accounts of Pallava, Chera, Chola and Pandya kings, as well as the hymns of Saiva and Vaishnava saints from the 8th century C.E., have been closely examined. However, the lack of specific references to Sri Sankaracharya in their inscriptions and Tamil hymns raises doubts about the validity of this recent narrative.
It is indeed perplexing why the proponents of the 788 A.D theory have not addressed this important question, leaving it unanswered.
