What is there to say about sensations?

SO working on the train, I looked up and took in the view from the window.

If we stop for a second and cast our mind around, what is the most basic thing we can say?

We might pick something out like: this table exists. Or the sky exists. Or we might go Descartes and go "I exist."

But there is something more basic, widely lauded by philosophers and artists alike: there is just the simple fact that "there is happening", for want of a better way to put it.

Whatever we may work out about what is happening afterwards, what we know right now is that there is happening, the world is present to us right now, and is happening right now.

Stuff is going on. The world is there, are senses are filled. And all this before we even think to put a name to any of it.

Perhaps there is a loud bang outside. The very first thing we get is the sound. Only after being alerted to this sound do we get thinking about what it is. Perhaps a car back-firing, perhaps a workman dropping something, perhaps even a gun.

This sense of there being "happening", of there being sensation, this all comes from what we later might say was outside. But before we get to inside and outside there is just the sensations. They just hang in the air, not belonging to anyone or anything. These sensations are the very first happening.

So where do sensations come from: the bright images in our eyes, the rising and falling sounds in our ears, the feelings in float in parts of our body, even the emotions: where do they come from?

I called it "The Source" before. There is nothing to say about these things that turn up at the door of our senses. It is like looking into a bubbling spring. That bubbling water fills our sense with no room for anything else. There is no room to ask what lies behind The Source, the bubbling up sensations of the happening are more than enough to fill everything. Afterwards we can examine this with our thoughts and mind, but in the moment of sensation we need for nothing more, there is no room for anything more.

Now its quite interesting just to sit back and absorb into The Source. What we notice is that there is no room for a self, or thoughts. They are squeezed out gradually as the happening, or the immediate sensations fill up everything. Sensations are disembodied, completely happy out there just as they are, just happening.
