1) The God you grew up with doesn't exist. 2) God exists. Duh. You just need to think bigger. 3) If you don't have stories with God in them, you go crazy.
I should note that the author also makes his living from coaching creatives, and if you have $1500 to throw around perhaps you should try it. However, I must say that one of my usual rants about "the occultism of small businessmen" is on the tip of my tongue - especially since, if you look at the material with knowledge of the author's vocation, you can see that this coaching is very like a mystical initiation into the Greater Work as we have defined it here. Does "The Work" automatically lose its value when you try to make a living from it? The work of Robert Fripp would suggest the answer is "no, but suddenly 99.9% of your time and energy gets tied up with bullshit, so best to be an amateur unless you have no choice". (As the Threshold Society says: "give freely".)
