It's only natural not to be able to focus on the "here and now" — the present is not a point, but a thick layer.

Not being able to return to the breath is not a failure

You are told to return here now. You direct your awareness to your breath. Three seconds later, you are thinking about tomorrow's meeting.

Many people feel that they are not suited for it.

However, one of the reasons it doesn't go well lies in the understanding of the word "now," rather than in our abilities.

There are no answers in the direction of time ticking away.

Let us think of it this way: the present is the boundary between the past and the future.

Then things get strange. There is no width to the boundary. If there is no width, nothing happens there. How is it possible to stand on a point where nothing happens?

Making the increments finer doesn't solve it. Even if you break a second down into a thousandth, that instant only approaches a point without width, moving further away from the felt sensation of "now" that is actually being experienced.

It's the same even if you replace it with an interval. Thickness is not a property that can be extracted by manipulating the time axis.

The present has depth.

When listening to music, what reaches the ear should be only a single note playing at that exact moment.

However, what is actually being heard is a melody.

The sound that just rang out is placed upon a layer where the immediately preceding sound has not yet completely faded away. That is precisely why it is heard as a phrase rather than a mere sequence of sounds. In phenomenology, this layer is called retention.

If the present were truly a point without breadth, music could never exist.

Reference and coexistence are separate events.

Suppose you happen to stop by the kitchen and catch the scent of incense. It is the smell of your grandfather's house, who passed away decades ago. You can explain that it brought back memories of the past. That is an explanation of referencing a point in the past along a timeline.

However, the feeling can sometimes be a bit different. Rather than having remembered it, that scene is here, inside this very moment, existing right alongside me.

Reference is a relation between two points on a time axis. Coexistence is a relation within a single present. The two belong to different categories.

And the magnitude of the separation adds nothing to this distinction. Whether it is a sound from two seconds ago or a scent from twenty years ago, as long as it bites into the current layer, the structure is the same. The fact that multiple things belong to a single place in a way that cannot be reduced to the order of the time axis is called structural simultaneity.

Trying to eliminate distracting thoughts does not work

When you try to focus by thinking of the present as a dimensionless point, your work ends up like this: you banish every just-passed sensation and every faintly anticipated next moment as mere distractions.

This is exhausting. Moreover, what remains once you've driven everything out is a narrow, empty place.

Looking at the present as layers, the work changes. Something is emerging right now. Just before it, there is something that has not yet completely faded. Even further back, something without a name is moving.

Instead of erasing them, leave them as they are, as things of different depths.

Concentration is not about narrowing down, but about being able to see the depth.

"Here and now" is the thickest place

Now, it is thought to be the thinnest place. The past is long, the future is vast, and only the present is a fleeting gap.

However, the order might be reversed.

Neither in the past nor in the future, it can only be touched within the layer of the present. The place that can be touched is always only here.

And here, the sounds of two seconds ago, the scents of decades past, and premonitions not yet put into words all coexist at varying depths.

Right now, this is not a point.

It is the thickest place.
