The Monkey mind

Our thoughts are forever changing in and out of our mind. If we train our mind, it will be better and less exhausive thoughts making us restless and tired. Is a calm and trained mind, a good thing ? Everything have both sides to a coin, whatever good , there is also something bad. Having a calm and trained mind is not all good. If the water breaks the wall or in a moment of lapse, the impact and stress could be higher and more stressful than a mind which is always hitting the extreme. This brings me to Robin Sharma's advise that if we let our mind go beyond a limit, there is a new limit. IF we stress our mind to another level, the new level is our limit. This advise seems to hold water and if we break our limitation each time, our mind and body will be strong. But, if we keep within a limit by controlling ourselves , our limit will not expand but rather it will shrink. Is this true to everything including our mind ? Is a controlled mind better to control ourself or a controlled lead to more stress ? If protect it all the time, it will not grow. If we message our brain through the many thoughts make us stronger or a stronger mind. Based on the Buddhist teacvhing, to have a train and controlled mind help to to be aware of our emotions and control it before it becomes worst. I would rather believe this wisdom as it has evolved through thousand of years. A train and controlled mind is a reverse of going beyond another limit. Rather, training our mind to be stronger and calmer is a new limit rather letting our mind go to create another new limit. it is very stutle and you will realize it when you practice on it. The mind behaves differently , it does become stronger it you let it good but rather preventing it go wildly is another new limit. Namaste.
