When things get tough, we are often stuck in thinking continuous thoughts about our difficult situation, and we are unable to break out of this unhelpful thinking. At some point, a moment of clarity will show up, and you will hear these thoughts. At that moment reach for a thought that feels better.
When you do this, you will find that The Universe will respond differently because of your effort, and your intention. Yes, you may fall back into the darkness of your thoughts temporarily, but remember each time you reach for something that feels better you will release a piece of the dark revealing more light.
Eventually, this massive field of darkness that you thought you would never find your way out of will reveal the light again. The dark never destroys the light, and it only hides it until we focus on it. Remember whatever we put our attention on becomes visible. This is not new age gibberish; this is quantum physics in action. This is how life works, and you always have a way back to the light if you look for it.
So remember to reach for a thought that feels better when things do not feel right and watch how the Universe responds to your effort to feel better. Staying in the dark is optional, and it is your choice whether to live there or in the light.
