So, when you say, ‘I have not done it’, there is one aspect in you that remains untouched by the consequences as well as the actions. And there is another aspect in you that is doing everything, and also suffering or enjoying the consequences. So, there are two things inside you.
There is a beautiful analogy in the Upanishad.
On this tree of the universe, two birds are sitting. One is enjoying the fruits of action, and the other is just witnessing it. This is the depth of the philosophy.
As you go deep in meditation and understand more and more, you will find these things happening. Whether it is very good work, or the worst job ever done, somewhere inside, you will feel that I didn’t do it, it has just happened.
Have you felt that? It has happened to me, I didn't do it. That is what it is. That is one thing which makes it happen. And the other thing is, feeling that I am not the doer. This ‘not-doing’ one, is the director.
