About genious people

I like thinking about art and genious people. It's always amazing when someone has a great talent and I'm very curious about what makes a person genious? I know, no one can answer this question, it's just a theory and different opinions. But still if that secret would be solved one day, it'll become a huge step for the mankind. Someone says that such people are blessed by God, someone thinks that they just use more percents of their brain. I don't know what to think but I'm sure no one can train their brain for it in purpose. It's like flashes of  the inspiration in some genious people minds. I've watched the TV programme about some writers' ability to predict some events. One such authors has written the story about one ship crashing and three people survived and twto of them ate the third one. After sometime it happend in real, can yo believe this? And the name of the ship was only one letter different from the name of that ship in the novel. After that I've started to think about that genious people somehow reach the certain condition of the consciousness when they can see something real what can happen like in yoga, you know. It's very similar condition to nirvana, maybe, and people can reach some space energy but they don't know what exactly happens to them.
