Disciplining body and mind..
Human mentality is often considered to be unstable. It is hardly settled by a single thought or action. It always lounges for newer things and actions. That is perhaps the reason why one thinks of the discipline. It is essential because it forces human mentality (mentality in the sense of mind as well as body) to act in a particular way or mode. In this manner, it surely takes away the freedom to act according to one’s free wish. But the favourable outcome is a result that is often not seen in short run. Or rather seen in the long-run.
To illustrate, take a look at the training which army soldiers undergo. That long, arduous and exhausting training is building the foundation for a soldier to survive in war situations. Difficult obstacles (kinds of exercises the soldiers are supposed to perform) test the mettle of the soldiers. On the other hand, they inculcate a habit of facing these kinds of situations in them. This habit is precisely the long-run benefit of the discipline.
Can we say that such discipline can work for mind? Well, there can be a strictly drawn schedule, according to which one has to perform the tasks. So that, the schedule becomes a habit for the individual. Once the person is accustomed to it, things become simpler.
