Mindfulness picks the objects of attention, and notices when the attention has gone astray. Concentration does the actual work of holding the attention steady on that chosen object.
Mindfulness involves the selective focus on particular thoughts or sensations, recognizing when one's attention shifts away from them. It serves as a guiding framework that helps individuals become aware of their mental processes, fostering a deeper understanding of the present moment.
On the other hand, concentration is the practice of maintaining a steady focus on the selected object of attention. While mindfulness identifies and acknowledges distractions, concentration actively engages the mind to stay anchored on a specific thought or activity, thereby enhancing the overall effectiveness of meditation and mental clarity.
