I'm also an advocate for sober lifestyle. I agree that eating mushrooms is not the way to find your inner light. What you will find is an illusion of inner light. I have only tried about three times. The second two were very light and mixed with chocolate. From just a few experiences I believe the projection is not of anymore value then say a movie. Its a presentation you can learn from. Its an email from perhaps Divine sure. The emails I've received from the Divine say that I could come back to find them when I'm sober.
If you really need a motivation to get sober and start meditating I think that they can lead you in that direction. I don't think the should be used religiously but perhaps ceremonially when you need a kick in the face.
