I’ve heard several deeply experienced, wise people from different fields talk about their varying experiences with enlightenment, or union, or loss of sense of self, or … whatever language you choose.
None are exactly the same but all have a few things in common.
One of those things in common is the notion that becoming fully aware (or, more fully aware) of all that is going on in the universe can be quite overwhelming, perhaps even disorienting or troublesome, if a person is not ready for it.
Of course, also magically amazing and very difficult to put into words.
You can experience this, or at least a small portion of this, practically any time, anywhere.
That’s because it’s always happening, all around you, all the time.
Even right now.
