We usually learn a new skill with focus and concentration. But Meditation is not the same way.
When we apply too much concentration on our mind, we try to direct it a very specific way.
Concentration is forcing the mind to remain or act to a specific way.
For a short time it might work. But later on, a cascade of thoughts will likely resurface, perhaps with more volume than if we did not exert this effort on our mind.
