S04 E19 - Evil tried to break thru the Yellowish-White Light

This event happened a few days ago. I was ready to go to sleep, but I wanted to check on the Yellowish-White Light from the Holy Spirit. When my eyes adjusted to the dark, I saw an Evil Spirit right next to the White Light. Then I noticed that there was a pool of what looked like black tar at the base of the White Light. I was shocked that Evil would try to attack the White Light. I just assumed Evil wouldn't even try to attack the White Light. They were unsuccessful.
