We are hear about artificial death, preserving the body with cryogenic fluid and reviving after some years.

Now assuming this becoming true after few decades, some questions are coming in my mind.

1. Will the mind go out of the body ?

2. If yes, then will the same mind come back to the body ?

3. Will the body remember the past and behave as the original person ?

4. How this phenomenon will have impact on the practice of Hindu knowledge ?
