  The Schr\"odinger's wave function can naturally be realized as an
'instantaneous resonant spatial mode' in which quantum particle moves and hence
the Born's rule is derived after identifying its origin. This realization
facilitates the visualization of `what's really going on?' in the Young's
double-slit experiment which is known to be the central mystery of quantum
mechanics. Also, an actual mechanism underlying the
`spooky-action-at-a-distance', another mystery regarding the entangled quantum
particles, is revealed. Wheeler's delayed choice experiments, delayed choice
quantum eraser experiment and delayed choice entanglement swapping experiments
are unambiguously and naturally explained at a single quantum level. The
reality of Nature represented by the quantum mechanical formalism is
conceptually intuitive and is independent of the measurement problem.
