I think our acharyal can be from anywhere in India. Many people from Kasi (U.P) and Gaya (Bihar) and from some other states used to be Final authorities and even Pareeksha Adhikari. Biggest Seat was at Kasi with lots of learned pandits who used to patronise the Kasi Mutt which was final seat. Now after some time, the north south divide happened and most of the Veda books which was mass printed in Kasi, stopped printing. In south, there was only one grantha printing press at Kumbakonam which also later closed down. One press which was run by the order of Maharaja of Mysore was also closed down due to poor patronage. Now, as you say, The Leader can be from anywhere, only he should unite us and lead in the path of knowledge.
