At the Oz Mix, Oz Fritz looks at the 23 glyph "as a viable and extremely useful technique for brain change."
Excerpt: "Like many fans of Robert Anton Wilson, when I first encountered his works and for several years after, I began having lots and lots of unusual coincidences with 23. Too many to write off as selective perception though there were some that fit that category. I usually regarded them as an indication of my awareness of a new life as a spiritual being, evidence of going in the right direction."
Definitely a read the whole thing post.
