I read an article in The Times the other day. It was about a man recently identified as Henry Molaison. I will paraphrase: Mr. Molaison lost his ability to form new memories in a brain operation that he underwent in 1953. Researches have been able to learn a great deal about how memory works in the brain as a result of Mr. Molaison’s unfortunate deletion. In one study that was conducted by Mr. Molaison and Dr. Brenda Milner of the Montreal Neurological Institute: Dr. Milner gave Mr. Molaison a simple line puzzle to figure out. The first day of the study was the first time that Mr. Molaison had ever attempted this puzzle. He was then given this same puzzle again and again over the next days, but each time was as if his first. Although he came to the puzzle each time with a true beginners mind, he became more and more proficient at the puzzle.
Now the exposition of Yoga is being made.
