"Through Time, Death, and Reality, the Metaphysical Adventures of the Man Who Fell Off Everest"
It's the story of a man who went to climb Everest in 1962. They were a team of four people. One of the guys paid the other to join him for expedition. The author was 21 years old then.
They tried not carrying oxygen tanks, neither did they porters. They did not reach the summit.
I've not finished the book yet. It kept me interested. I guess, in the later part of the books, the author wrote a lot about his philosophy.
One thing interesting about him is, he has a glacier named after him in Antarctica. It was before he went for Himalayas.
