Advent of Shankaracharya : Tunga Adherents’ uncertainty in 1958 & Advocate Krishnaswamy Iyer’s Admission

In 1958, Advocate Krishnaswamy Iyer, Tirunelveli, a staunch adherent of Tunga matha in his book published by the Srirangam Vani Vilas Press, reveals that even at that time, they lacked clarity about Shri Shankaracharya’s birth year, His establishment of four mathas, or Kedara as His place of Siddhi. Iyer justifies the absence of evidence, dismissing such debates as unproductive.This prompts the question: how, why and when were their baseless theories- 788 as His Birth year, the founding of only 4 mathas and kedara as his place of siddhi – systematically planted and propagated by the adherents of Tunga Matha when they themselves were not aware of thse details even in 1958?
