A person's mind is a powerful tool. In one sense, it is the same situation as having a loaded gun. Both are very useful and have their purpose, however, there are times an individual may not really realize or understand exactly how powerful each of these possessions can be. The mind or a gun can each be used either for the right or the wrong. It just all depends who is using them.
A mindset is more powerful than any circumstances which may affect your condition or status or position, and any circumstances which may cause momentary afflictions or pains, and even suffering.
