Shanon also sees signs of a hallucinogenic vision in the story of the burning bush. "Moses 'looked, and, behold, the bush burned with fire, and the bush was not consumed,'" Shanon quotes from Exodus 3:2. Time passes differently when under the influence of the plant, he notes. "That's why Moses thought the bush was not consumed. It should have been burned in the time he thought had passed. And in that time, he heard God speaking to him."

I just realised, religion makes a shitload more sense if you assume everyone involved was high as hell.
