Hi Inventech5,

It's complex, from what I know, it's possible to stay many hours in a focus state.  But soon or later, the meditator would receive huge signals from its physical body and would be pulled back by it (it needs water, or food, or to go to toilet, or anything else)

I guess that with enough determination, the meditator would be able to ignore those signals... and eventually his body would die.  

My guess number 2 is that with enough practice , the master meditator would be able to control the dying process by putting the body into hibernation state... but  soon or later, the body would die.

Why are you wandering about that?

I have read that some meditation practitioners in some cultures have been able to accomplish this feat, at least in the past. They meditated until their deaths, even controlled the preservation of their bodies (mummified) at death.
