The human brain is a magnificent tool, it accomplishes many amazing things by breaking things into smaller pieces for them to be more easily understood. However, when we view reality through the brain there is an abstraction process that data goes through since the brain functions in that manner.
Let us think about an example of that process:
Scientists (who are pioneers of abstracting reality through the brain tool) try to explain to a person who has never seen an elephant, what an elephant is. They describe to him the height, color and many more visual impressions, they can also mention the biological data about the elephant and the genetics of the elephant.
Now, all of those descriptions come from the brain and are a product of the logical process which the brain operates on. When that person actually sees an elephant and experiences it (vision, smell, touch etc) that experience, could never be explained by the brain. The texture of the elephant's skin may be describes as rugged but the texture of crocodile skin and armadillo skin also fall into that category, but they are not the same experience.
In the same manner for many people their brain is constantly limiting their view of reality, by identifying themselves with their brain chatter they become trapped in the abstraction that the brain puts out into their consciousness.
The brain tried to understand reality by division, compartmentalization and definition. The reality that we live in, however, is a giant fractal. The logic may break down an object to smaller particles, but those particles may be broken down as well. This process goes to infinity, thus the brain can never truly "Get to the bottom of it".
In various meditation techniques the goal is to let go of the brain chatter and to experience reality as it is, without the logical tools of analysis abstracting it. A similar event happens when people watch something like a sunset, a beautiful flower, their child or a majestic mountain.
A very good tool for detachment from the abstraction is to remember a time when you experienced the moment and bring back that feeling to your present moment, whatever it may be.
So as said in many forms, many times before
Think less, feel more.
