In Chapter 4, Joe Dispenza delves deeper into the concepts alluded to thus far and provides another practice for readers to try. First, he covers the visible light spectrum to illustrate that there are frequencies that humans cannot see or perceive, but that exist nonetheless—for example, radio waves and X-rays. Visible light is only a fraction of the electromagnetic frequencies humans can perceive. He explains wavelengths—the higher the frequency, the shorter the wavelength, and vice versa—and how cells communicate with each other by transmitting info on different frequencies of light (89). He mentions these concepts to assert that, if people only define reality by their physical senses, they may be missing out on a lot of other information, as even frequencies that humans cannot sense still exert influence. Sitting still in meditation and tuning out the external environment can help a person get a clearer signal and receive information from it. Tuning into this new light and information allows the body to experience order (“syntropy”) instead of disorder and quiets down the analytical mind.

He alludes to the meditation at the end of the previous chapter—he had asked the listener to pay attention to different parts of the body and the spaces around them—and explains in this chapter why he included these instructions.
