I strongly doubt that the body is still alive, atleast most of the body functions and the vital ones, but i wonder if there is any support or state of conciousness, awareness, thinking, feeling, in connection to the soul of this person/monk.
Cases of mummifications by natural causes can be also found elsewhere around the globe. Unfortunately, the corpse hasn't been found in it's original position & place, which would allowed the scientists to study the environmental conditions and come close to the causes of the mummification of this monk. Still, i think, other examples of (naturally or technically) mummified buddhist monks' bodies exist in Asia.
