...  Nisargadatta's teachings also focus on our notion of causality as being misinterpreted. He understood that the interconnectedness of varying forces in the universe is so vast and innumerable that the notion of causality, as presently understood, is wasted. The endless factors required for anything to happen means that, at most, one can say everything creates everything; even the choices we make are predetermined by our genetic code, upbringing, mental strivings and limitations, our ethical and philosophical ideals, etc., all of which are uniquely combined to each person and recontextualized accordingly.
This leads to the radical notion that there is no such thing as a "doer". According to him and other teachers of Vedanta, since our true nature or identity is not the mind, is not the body, but the witness of the mind and body, we, as pure awareness, do nothing. The mind and body act of their own accord, and we are the witness of them, though the mind often believes it is the doer. This false idea (that the mind is the self and responsible for actions) is what keeps us from recognizing our Self. Nisargadatta cautions:

"The life force [prana] and the mind are operating [of their own accord], but the mind will tempt you to believe that it is "you". Therefore understand always that you are the timeless spaceless witness. And even if the mind tells you that you are the one who is acting, don't believe the mind. [...] The apparatus [mind, body] which is functioning has come upon your original essence, but you are not that apparatus."
