We do not perceive the physics, even when it is physics. We do not perceive sound waves (unless subsonic. lol), we hear sounds. Just as we do not perceive photons, we see things. In both cases we have receptors and transducers, so that the signals are processed in a meaningful way for us.
More emotional states look similar. A lump in the throat, choking on words, is an experience - few perceive it as some block in energetics, or a choked chakra. Such experiences can be measured - it just means using the right instruments. But to know what those instruments should be requires a tentative hypothesis. Like Royal Rife says he scanned millions of frequencies till he found some resonances.
Reminds me of Louise Hay's work. There was a time when I had really dipped deeply into the language of the body! First it was Bioenergetics, which then lead to all kinds of other books on the subject. I was so fascinated by how much of our language reflects our moods or diseases or bodily pains and tensions. I subsequently did a lot of therapeutic work both on myself and others, using this knowledge. It's amazing what is often locked in our bodies, and how it comes out in our language. That guy is a pain in the neck.
