Why did this musician develop laryngitis before vocal performances?

Interestingly, this was not karmic but does add to a karmic pattern of having his body fail him in some way or another at key moments requiring him to perform in some way and gain something for himself. This was a manipulation energetically to impair the vocal cords, so it was an example of targeting with a very specific intention, knowing his schedule and wanting to trip him up and make him vulnerable so he could not perform effectively. This is why doing the Lightworker Healing Protocol is so important to prevent such things from happening, at least given enough time to lower their interest in him personally, and eventually drop from the list of targets.
