Abstract: A new wave-particle non-dualistic interpretation for the quantum formalism is presented by proving that the Schrödinger wave function is an `{\it instantaneous resonant spatial mode}' in which the quantum particle moves. The probabilities in quantum mechanics arise only for the observer's perspective due to the nature of doing experiments but they do not exist in Nature. In other words, quantum mechanics itself is not a probabilistic theory. This view-point is proved by deriving the Born's rule by showing it to be equal to the experimentally observed relative frequencies. Also, it is shown that the classical and quantum mechanical times are one and the same. By identifying the already inherently existing mechanism for the collapse of wave function within the quantum formalism, the present interpretation naturally proves why the Copenhagen interpretation is very successful in explaining the experimental outcomes. The Young's double-slit experiment, the Wheeler's delayed choice experiment and the Afshar's experiment are unambiguously explained at a single quantum level. Both `measurement problem' and `retrocausality' are absent in the present non-dualistic interpretation of quantum mechanics.
