A cook touches a very hot utensil accidentally and automatically the body pulls the hand back.
An electrician touches a high voltage live wire accidentally and automatically the body pulls the hand back.
The above two examples are the illustrations of how things happen automatically without us doing them consciously. These actions happen via defence mechanism thanks to the nervous system.
It is easy to see via both of these examples that we are not the doers. However, when it comes to other acts like speaking for example it is not so easy to see that things are happening on their own. We often tend to own the doership. This is because, while tuning of attention does happen automatically, it happens so quickly when attention keeps on drifting from one place to the other that our conditioned intellect is unable to catch the autopilot behaviour. When this fact that everything happens by itself is recognised by watching the activities of body-mind, e.g. the appearance of thoughts, movement of hands, words coming out from mouth, happening of hearing via ears etc., the astonishing realisation that I am not doing anything and everything is happening by itself takes place (also refer to Bhagavad Gita 5.8, 5.9). After the recognition of this fact that if everything is just happening and I am not doing anything and this body-mind is like a robot, the question, “Who am I?” is natural to come. Seeking of the answer to this question may eventually take the seeker towards enlightenment when the seeker after finding itself sees itself everywhere.
