Then what about for example chakras? They are important as an esoteric concept. Are the chakras real? Someone said that the chakras are only symbols and not actual energy centers. But Candace Pert wrote in the book Molecules of Emotion that she as a neuroscientist was shown a drawing of the chakras by an eastern guru and when they put the drawing on top of a picture of the human nervous system, the chakras aligned with nerve centers along the spine. So I believe the chakras are real energy centers.
I can also simplify it and say that kundalini is simply the tensions in the body and mind. That's consistent with kundalini representing a trap of being caught in only duality. The lack of oneness realization causes the tensions. And the tensions in turn cause the spiritual entropy Ra has talked about and so on, so that's a simplified model that can be unpacked into more detailed descriptions in the form of chakras etc.
