I first heard of the idea of “Monkey Mind” through a book that was recommended to me by a counselor. I had never heard a more accurate description of what so often goes on in my mind! My thoughts not only jump around like monkeys in the trees, they keep returning to the same branch over and over. It is a combination of not being able to calm the mind, jumping from thought to thought, and dwelling on all of the hurts, injustices, mistakes, angers, and slights that ever happened on what another book called “the playback loop from hell.”
This article is a short but good one on the subject.
