Oh boy, I have had this event happen a couple of times and until such time as you have faced your own darkness this will never really go away. My last one was the most memorable and most effective!
The dark night of the soul is a process many spiritual seekers go through at some point in their lives and is not mentioned that much in spiritual texts. The most common advise from the general enlightened ones are for you to raise your vibration….this too shall pass, take time out, relax etc etc.
The dark night of the soul is an overall beautiful experience where a person’s ego/false self is “dying” in order for their true, Higher Self (which is LOVE) to emerge. We basically realize the ego self is false and never really existed.
