As so beautifully described by Reiki Master Bashir Kevin Cates, our minds are merely "random thought generators". Each and every thought should be considered a living entity, one that is born, has a life, and dies. What determines the life span of our thoughts, is how much energy we "feed" them. The more energy or emotion put into a negative or positive thought, the larger this living thing becomes, and the longer it lives.
It is very possible to restructure the way our minds generate thoughts, so that we are not bombarded with those that do not serve us. It all comes down to which thoughts you choose to give life to.
