My Master (Babaji) once told me a story about three people who went to Himalayas to meditate.
They went up the snow-clad Himalayas, sat down and meditated. After a year, one of them opened his eyes and said, “It is quite cold here”. Then, he went back to meditation. Another year passed. The second man opened his eyes, and said, “I think you are right”. Then, he too went back to meditation. At end of the third year, the third man opens his eyes and says, “Why don’t both of you just shut up and meditate?”
