Simply Mind boggling [ and hence me blogging] truth.

"The argument for the soul not undergoing these changes is that it observes all these changes. The observer of a change is not affected by the change or he ceases to be an observer. A man sitting in a moving airplane and unable to look out the window cannot fathom its speed, but a man on the ground observes it easily. Similarly, everyone has the experience of the six types of changes occurring in his own body, but the observer of these changes is not the body. The observer is the soul. This is logically inferred. Hence the very experience "I am miserable" proves that I (the soul) am not miserable, because if I was miserable I would be unable to perceive the misery. "
