(6.7) Concentration is the highest personal achievement that can be acquired. It is the distinguishing characteristic of every successful person.
Mind is in a constant state of activity. Concentration is like tuning the radio dial so that you only hear one station clearly. This happens naturally when we are so completely absorbed in a situation that we are conscious of nothing else. More often than not, this takes work because it is rare to be so absorbed.
It takes work because mind is already active and we must consciously introduce a new dialouge that can drown out the rest.
(6.8) Concentration may be acquired by faithfully practicing mental exercise.
Mind is programmed to ruminate. As long as it’s ruminating upon a dialogue that supports our ideal state, we will benefit from this process.
Rumination is the process of mind that seeks to resolve the reason for phenomena.
