We are what we think. After procssing in mind/brain , that will be executed by our own actions I.e., may shouting at others (anger-shown in verbal form, beating other in touch) . The whole process is will be running in brain/mind initially , then executed but we see only one side of excution part and we can not see other part which has taken in our mind. Thats why we say “MIND YOUR WORDS” not use the word brain.
Mind is invisible & intangible , can not be seen anywhere . It does not require space like brain box.
Any invention ormdiscovery starts as thought in mind , it is a bundle of thoughts arising or we can say it as a store house of thoughts or emotions which control the way we live our life.
