I can offer a couple of points on why I consider it a subject of great significance.
[1] On a personal level, which you are of course free to disregard as anecdotal, I had such an experience myself. Twice to be precise. So I know that the source is indeed experiential (“mystical experiences exist”) though I would not yet claim that they necessarily point to an underlying reality. What I would claim is that they certainly need to be explored and not disregarded as a ‘misinterpretation of sensory input’. My personal observation is that (when naturally occurring not chemically induced!) they accompany a psychological breakthrough through an increase in experiential (in contrast to rational) knowledge.
[2] Ancient foundational texts of major civilizations have a mystical basis. Good examples are the Upanishads and the Teo Te Ching but the same experiences can be found in Hebrew, Christian and Sufi mystics, the Buddha, etc. A look at the evidence will immediately reveal that the experience is common among all these traditions and also seems to have been reached independently. We can then observe that this experience is present in the most ancient layers of our mythological structures. The attempt of abstracting the experience into an image can be seen, for example, in symbols such as the Uroboros which point to the underlying archetype. The Uroboros, Brahman and the Tao are all different formulations of the same underlying concept. If we then take seriously Peterson’s hypothesis about the basis of morality in stories things get really interesting; but I am not going to expand on that point here.
These are by no means the only reasons. Indeed the above points seem quite minor when viewed through a deeper familiarity with mystical traditions. But we have to start somewhere I guess.
