Be mindful of the kinds of thoughts that you allow into your mind. The comet represents a 'passisng' thought that causes way more 'damage' than you would first expect. As far as our solar system goes, the sun is the center. It symbolizes your center of thought, life, etc. The damaging thought causes damage to your main focal point. Look at your life and what's been going on around you. See what kinds of thought you are allowing to 'pass through your universe'. For example, someone may find themselves with a fearful thought, or catch a rumor or piece of gossip. This leads to dwelling on the negativity to the point where you lose focus of or begin to doubt your faith. This could be about your actual faith, a financial goal, wedding plans, etc.
You are seeing or feeling the evidence of this event. Isolate the damaging thought/thinking. Get rid of it by holding on to the truth, and refocusing on what's important. Hope this helps. God bless.
