During the process of transformation, people elevate to new and higher levels of consciousness. When people elevate to the next level, some feel uncomfortable for a small period of time as they adjust with the new situation in their life. For example, if you are living in the dark and suddenly somebody turns on a light, your eyes need some time to adjust with the environment of light. In the journey from darkness to light and from light to even greater light, in every new situation, people feel a little discomfort while adjusting to their new environment and state of being. The discomfort during this period of adjustment is what we call a “healing crisis” and will resolve itself over a short period of time.
