Not through psychedelics, but through a mystical experience. Mystical experience has been quite well described in Wikipedia, while it is not explained there as I see it. I am referring, in particular, to the rarely manifested version of it which is produced by the human body solely. Therefore, it does not require psychedelics or meditation to appear. In my article I look for an explanation of why such an unexpected experience exists in the first place. I have noticed that it has roots in the distant past of our species, in the consciousness and its activities, in human mental adulthood, and also in the psychedelic world. I’ll try to keep it sensible and logical.
