What is Ultimate Knowledge? Ultimate Knowledge defined as the knowledge of all is not possible for a human person...it isn't even possible for a non-human thing,(i.e. a computer), and I also don't think that a spiritual or Godlike creature can have ultimate knowledge. So no, you can't gain Ultimate Knowledge...but I believe supernatural powers do exist, otherwise how would you be able to explain some of the things that happen in a supernatural sense? As to what you need to unlock such powers...I don't know maybe just luck and being in the right place at the right time...or maybe it's not we who choose the power, but the power that chooses us!
