SWIM asked me to transcribe this:
"Ever read The God Gene?
I am personally an omnist/omnitheist, that is, I follow the post-structuralist actualization of personalized spirituality...basically, I believe that there does indeed exist a spiritual dynamic, as evidenced by the cross-cultural universality of certain forms of spiritual experience, however our interpretations of it through language are clouded by our cultural context and thus, organized religion is the result of cultural phenomena rather then spiritual experience. Despite my beliefs, I do realize that the universality of some spiritual experiences, such as OBE and "all is one"/"supreme connectedness" could, in fact, be interpreted to mean that spirituality is simply an affect of biology...
My spirituality has been solidified by a number of experiences but the most important of these was an experience brought on by the substance LSD. I underwent a variation of the "all is one" experience that was isolated to my intellect, that is, I felt for a moment as though I was unified with the noosphere (collective consciousness of all thought and idea) or that I was engulfed by the intellect of a supreme creator. This personal, spiritual experience was extremely powerful and important to me, and it, along with others, made me progress from being a staunch atheist to an agnostic to an omnist.
However, just because I do indeed believe in a form of spirituality and am a spiritual person, this does not mean that I cannot come up with atheistic explanations for the experiences I have had. The book, the God Gene, pulls from various research sources and hypothesizes that there is a collection of protein-encoding genes that correlate with spiritual belief and/or religious behavior. This gene is related to protein synthesis in the serotogenic system (5-HT) and what do we know about the tryptamines and phenethylamines? Well, they act only on the serotogenic system! It is therefore at least a possibility to suggest that these substances may promote the expression of the so-called "God gene".... I mean, if phenethylamines and amphetamines can change the texture of peoples hair and lighten or darken their eye color by effecting gene expression, why can't tryptamines and phenethylamines effect gene expression in this way?
IMPORTANT NOTE: I am not suggesting that any tryptamine or phenethylamine is a mutagen, as countless studies have confirmed this not to be true, however, GENE EXPRESSION has nothing to do with the integrity or form of DNA, it in fact, has to do with the integrity and form of Histones, proteins found on DNA strands that dictate the shape and density of the strand as well as repress and activate certain genes."
