The capacity to gain an accurate and deep understanding of someone or something! The dictionary meaning does not give us an explanation of exact experience. It is often linked with intuition as the understanding or clarity attained within our mind may not always be backed up with facts, figures, evidences or series of experiences. Of course all these factors do contribute in getting insight into something but the experience of insight is not limited to them.
Our brain has tremendous power and capacity to observe, note, record, store and process enormous information. The information could be fed in pieces but the brain processes it based on need and holistically. It also depends largely on how do we train our brain. It has a capacity to collate the scattered pieces of information, connect the dots and create something new which wasn’t fed to it as is.
Insights do not happen to anybody overnight. One must develop certain habits of observing, absorbing relevant information, questioning, assessing, analyzing, challenging and being open to anything that comes up after the churning of thoughts. Very strong beliefs, filters and assumptions do not allow us to lead to this experience of insights. It is a sense of realization that is offered by our own brain, giving utmost and unquestioned clarity into the relevant thing or experience. At times such insights are beyond a logical and rational explanation, where we connect them with the intuitive powers and the accuracy of them can be justified only in future events.
I do believe in such powers of brain… many of us reject or ignore such voices getting from within. I must say that if you remain honest with self, such insights give miraculous results.
