Acharya Prashant explains that concentration is not a matter of applying a specific method but of understanding the nature of the mind. He states that the mind naturally wanders due to external stimuli and sensory attractions, which are often beyond an individual's control. Instead of trying to stop the mind from wandering, one should focus on being aware of its movement. He describes the mind as a bird that seeks to fly or a restless child that becomes quiet when observed. By simply watching the mind's activity without fighting or suppressing it, one becomes its master, and the mind eventually settles.
