When we have to use the mind and do a task, instead of simply doing that thing and using a little bit of mental energy, we tend to use so much more. Our mind spins into worries; ‘Will it go as I hope, or not?’ Although it is only necessary to use one pound, we are wasting thousands of pounds of mental energy. We thus build up stress in our mind.
As we practice meditation regularly and get better control of our mind, we can simply apply the mind to its best focus on a task, then when that task is over we can keep our mind quiet. We don’t have to be brooding about it at all – we would be able to stay relaxed and peaceful in the mind.
