Mainstream science has been catching on to the fact that non-physical aspects of the human being are not only real, but they can be grown and developed into powerful tools for personal development and use. One of these aspects is intuition. So, what exactly is intuition? A good way to describe it is a gut feeling, a sense or a feeling about something. It's arriving to some sort of truth about something, an event or experience without using any type of analytic reasoning. Intuition has been measured, which is why the US Office of Naval Research (ONR) admitted to developing methods to develop and measure this phenomenon for their soldiers.
