I might remembering the specifics incorrectly, so be flexible with my description.

I think it starts with a main character. He’s quite a moody guy and then he hears about this Indian guy who goes to a doctor to cover his eyes with cloth. and I think he asked them to tie it very tightly. Then the Indian guy walks out and he can just see where he’s going. Then the main character is really interested in how he’s done this, so he goes to the jungle in the middle of nowhere and he finds a really remote area and he finds a teacher and he starts to learn how to meditate. There is a scene with hot coal where he learns how to walk on it possible something about snake charming? The book has kind of a weird and long name.
