Our thoughts eventually become our reality. I learned that experts calculate the average person has about 50,000 thoughts daily. Many people, including pastors, teachers, and law of attraction coaches tell us that our thoughts can become our things. One interesting realm of human philosophy is the notion that your thoughts are not your own, but rather coming from a collective consciousness or outside force in the universe. These types of religions are entering the western world in many ways such as the spiritual movement.
One cannot stop the incoming thoughts from the universe, only suppress them. For instance fear or severe stress will initiate a fight or flight response or even cause one to think about what potential actions to take. So is this actually a revelation or is it applying unknown quantities to known psychological responses to prove a point and ask you to deduce the rest? But if one does get a thought or impulse and chooses not to act on it, even if the thought was not one's own, one can control it by choice; it is the same thing as denying the thought a place to grow. It is therefore exhibiting free will.
If in fact the thoughts are coming from the universe, then you have the control over said system as well. So in this scenario, an entity which can control his own thoughts controls or causes change to a large degree. All thoughts should be observed whether or not they are acted upon. You can learn from thoughts, regardless of how you come about them, through intuition, observation, and experience.
