re: Am I a figment of my own imagination?
In a book called "The Rabbi', by I've forgotten whom, read about 30 years ago, the old rabbi is talking the young rabbi through a crisis in faith.
Finally the old rabbi says, "I can't prove there is a God, true. You can't prove there isn't one. So each of us is left to believe what we want."
Or words to that effect. I rather liked it. Had an impact on me just as I was getting sober.
