The stress hormones we experience while living in survival mode give the body a high dose of energy and cause the five senses—which plug us into external reality—to become heightened. So naturally, if we’re continuously stressed, we’ll define reality with our senses. We become materialists. When we try to go within and connect with the world of “non-sense” and the immaterial, it takes some effort to break our conditioned habit and our addiction to the chemical rush we get from our external reality.
