When my career began, the professional niche of "spiritual teacher" didn't exist. This served me well, because if you don't think there is anything to be ambitious for, you're not ambitious. And ambition gets in the way of anything having to do with spiritual transmission.
To be ambitious is actually to doubt God. To be ambitious is saying, "I need to walk ahead of God here, I need to make something happen." The spiritual life is not where you are making something happen, the spiritual life is where you're allowing everything to happen. And that really is what this course is about. This course is about moving from dispensing information to actually allowing your consciousness to be on some level a conduit for transmission. In A Course in Miracles it says, "People hear you on the level that you speak from."
