Hi Daniel
Thanks for posting this link.
I see two issues here. One is claims to attainments. The other is buddhists being disturbed by the extreme views propagated by actualists and whether such views have a place on this site.
Why are claims of attainments so threatening? To me what is worse than claims of attainments is misplaced confidence. What can we be truly confident of in this life? Direct experience. Period. Confidence in any ideas or philosophy is misplaced unless it is ones own philosophy derived from direct experience and open to change as new experience arises.
I do not hold to the absolute superiority of arahatship or actual freedom, but instead am open to the exploration of both ways of seeing. You could say I have no dog in this fight.

But I see battle lines being drawn, and I sigh at the inevitability of it. If you have ever thought that words fail to do justice to nonduality, you've barely scratched the surface of the inadequacy of words to describe the affective-free state to someone in an affective state who doesn't recall an affective-free experience of their own.
To challenge love, imagination, being itself... forget magick, this is the devils work. This will get you burned at the stake. These concepts challenge parts of us which take years to let go and find equamnity in the prospect of no-being. I am speaking from direct experience here.
I have personally found that the meditative/investigative journey of actualism is in keeping with the spirit of this site, in much the same way that people from a magickal background or a christian background can discuss practice here too. Let's not presuppose an endpoint of development whether arahatship or otherwise, but instead be open to all forms of development.
