Theory of everything must include consciousness. In Part I of this series of 3 articles, the subjective experience (SE) aspect of consciousness was introduced in classical physics by examining the invariance of various components of theories under PE‐SE transformations, where PEs (proto‐experiences) are precursors of SEs. We found that (i) classical physics is invariant under the PE‐SE transformation, (ii) potential SEs are embedded in space‐time geometry for the structure of space‐time in superposed form, (iii) potential SEs can move with spatiotemporal coordinates of matter for matter field because both mental and material aspects are always together in the dual‐aspect‐dual‐mode optimal PE‐SE framework, and (iv) our specific SE is the result of matching and selection processes and can change with space and time. For example, experiencing redness has neural correlates of V4/V8/VO‐red‐green neural‐net with redness state. When a subject moves, the specific SE redness also moves with the subject’s correlated neural‐net. In the current Part II, the SE aspect of consciousness is introduced in orthodox quantum physics by examining its invariance under the PE‐SE transformations. We found that the followings are invariant under the PE‐SE transformations: Schrödinger equation, current, Dirac Lagrangian, the Lagrangian for a charged self‐interacting scalar field, and Standard Model (the Lagrangian for free gauge field and Lagrangian for the electromagnetic interaction of a charged scalar field). In Part III the SE aspect of consciousness will be introduced to unify it with fundamental forces in loop quantum gravity and string theory of modern quantum physics. All parts together lead us towards the theory of everything.
