The concentration has a lot of issues.
Why are there so many people still concentrating on something?
When the mind is in control,
When the concentration takes place,
The mind can enter into a state which feels like peace and calm during that concentration.
Actually,
Because of this control,
Other thoughts can't pop in temporarily,
So the mind feels peaceful artificially.
So in that concentration,
There's a pleasure,
That's instant pleasure,
That other thoughts are not into the mind due to the suppression,
Due to the control of the mind.
So the mind is seeking pleasure from the concentration.
And there are different names to that called the flow of whatever.
So the mind forgets time and do something for a long time,
Maybe for the whole day,
Without realizing how late it is.
Because in that moment,
The mind forgets the self,
The mind forgets the trouble and is present.
But the self is never gone,
The trouble is never gone.
The self is only absorbed,
Suppressed,
So is the trouble.
When this confusion ends,
When this control ends,
The mind needs to return to the balance.
And this process of returning to the order is full of chaos.
The mind becomes chaotic again,
Turbulent again.
But it is a normal process for the mind to return to the natural state where there's no control.
But this process is not present.
And the mind rejects anything unpleasant,
Including this.
So the mind seeks a new way of concentrating,
New attachments,
In order to keep the mind in that state where the self is forgotten,
Where the trouble is forgotten.
So you see,
Concentration becomes so popular among people due to this.
