Is mysticism mysterious?
It’s certainly presented that way in popular culture. And perhaps for a couple of reasons. There isn’t a widespread understanding of what it’s about, so it naturally may seem a bit mysterious. And what it’s about isn’t so easy to put into words.
And yet, it’s not inherently mysterious. Not any more than most things. At least when we have had a taste of it.
As I like to say, it’s about noticing what we are, which is what our experience happens within and as. We can call this the awakeness (or consciousness) all content of experience happens within and as. And from here, it does seem as if the whole world is this awakeness. It seems that this awakeness is what takes all these forms, and locally may temporarily take itself to be a separate being – even if the ultimate identity of everything is this awakeness.
Most can have an immediate and direct taste of this through, for instance, forms of inquiry such as the Big Mind process or the Headless experiments. (Some also do by using psychoactive substances but I wouldn’t recommend that.) And after this taste, most of us will need to clarify and stabilize and learn to live from it over a long period, usually for the rest of our lives.
As with most things, we can explore this endlessly. For those who us who have, for whatever reason, a fascination with this, it’s an endless exploration.
