Perhaps a simpler way to think of this energy is in regards to our attitude. Our attitude corresponds to our energy. If we have a negative attitude, our creations and situations will follow suit. Sometimes, it may be hard to determine if a negative attitude caused a bad situation, or a bad situation caused a negative attitude. But in reality, nothing is random. What we are experiencing, we created at some point. Everything that transpires in our lives is karmic.
Whatever the quality of our energy, we need not get distressed over it. We can overwhelm our dark energy with an abundance of light just as well as the other way around. The goal, therefore, is to infuse our mind with the good stuff. This is no small challenge when we consider the years of bad stuff that has been programmed into our minds.
