The Third eye
As we all know the two physical eyes are just sensory organs. Through which we see the world and perceive things as per our conditioning of our Minds. They feed the mind with all kinds of nonsense, because what you see is not the truth. The opening of the third eye means , you are aware of your Mind and its activities, thought/thinking as it happens. For me , the observer in you, which observes the thought as it arises in your mind is the ‘Third eye’. The opening of Third eye means that , you are aware whats going on your mind and can literally “see” what is going on your mind . People say that , if Shiva opens the Third eye the world is destroyed etc., What it means is that , if one is conscious and aware of one’s thought/thinking as it arises in the mind, it destroys the ignorance in you. That is the destruction of illusion. You are ‘Shiva’! Don’t believe that you are your Mind. This is delusion. Consciousness arises when you start watching the ‘Thinker in you’. When you start watching the thinker in you, all the chatter that goes on and on in your Mind stops.
So when you listen to a thought, you are aware not only of the thought, but also of
yourself as the witness of the thought. As you listen to the thought, you feel a conscious presence – your deeper self – behind or underneath the thought, as it were. The thought then loses its power over you and quickly subsides, because you no longer energizing the mind through identification with it. And this stillness of the Mind is the beginning of the end of involuntary and compulsive thinking and the beginning of arising to your natural state of oneness with the universe.
