The same principle applies to fear! Fear is guaranteed to come up in our lives over and over and over again. If we focus on it in any way, we create problems for ourselves. If we focus on it enough, we can drown.
Here's how it works:
Fear comes up - we're human beings, so that's a guarantee. But if we allow ourselves to be drawn in by the fear, focus on the fear, listen to what it's telling us, think about it, mull it over, resist it, or - God forbid - act on it, the fear will get bigger and bigger. It will continue to nag at us and it won't go away. It will create problems for us in our lives.
But if we recognize the fear for what it is - a momentary flux of energy - and allow ourselves to feel the feeling without resistance, and then immediately turn our attention away from it by focusing on a more positive feeling, such as peace or joy, the fear will evaporate. And if we do this every time fear comes up, we will soon discover that we have created a life condition of joy.
The great thing about nature is that it is constantly offering us assistance in the form of valuable lessons. We just need to be open to receive them.
