The cave at Hira and the importance of place to mystical experience

I've long been fascinated by the earliest "revelation" received by Muhammad, which he interpreted as being from the angel Gabriel. I believe Muhammad's experience in the cave with the Angel Gabriel was real. While I accept that Muhammad is the only valid source for what happened to himself, I am also convinced that the orthodox interpretation of the experience is only one of a range of possible interpretations one could have given to it. For instance, if Buddha Gautama was in that cave, I do not think he would have spoken of the Angel Gabriel, for the Angel Gabriel would have been culturally alien to his worldview.

When I step back from Muhammad's interpretation and think about the sacred space of Hira, the impression I'm left with is the fundamental importance of that cave as a 'gate' to another reality, where there is always the potential for humans to have an experience of, an experience that lies beyond the sensory world of common sense experience. All revelation and mystical experience in human history, if it is not the specious invention of a complete charlatan (a possibility!), is made possible by the intersection between these spaces and the personalities of certain sensitive individuals.

In studying the life of Muhammad, I've come to understand that it is only natural for one who has such an experience to interpret it through the lens of their own linguistic and cultural frame of reference. And I also hold out that it is always possible for the one experiencing this to misinterpret its meaning, since even the greatest of humanity are potentially unreliable guides to an experience that by design overwhelms one's senses and sense of normalcy. These interpretations in language are almost always a partial understanding of phenomena that remain fundamentally mysterious. But I am convinced there are other places on this earth very similar to Hira cave. This is actually one reason I can think of why the recovery of indigenous epistemologies is very important work, not only politically, but spiritually.
