I am not the doer, so am I self realised

I now know that I, the person is just the play of nature, me, the spirit is just the witness, experiencing the nature playing with itself. Is this what they call self realisation or is it something else. Mind feels like a 6th sense, which feeds me thoughts like ear feeds me sound. All beings have the same self within. If this is not self realisation then what it? I know that I have found something profound but I am confused with labels, is this self realisation, enlightenment or something else. Maybe my brain just realised the philosophy and it is something else. What is self realisation in this context.
