Would this wider scope be an advantageous prayer? “Source Creator, each and every day, remove or render harmless all dangerous viruses and other organisms, all heavy metals and other harmful substances at toxic levels [and all other SCOURGES], from myself, my loved ones, and apply this prayer again and again as needed to help all affected beings and the Earth as a whole [and the rest of the Free Will Galaxy], to keep everyone safe, and restore well being to the afflicted.”

Again, you can pray for anything you like, but we see issues in expecting this to be embraced by the masses because they will not at all understand what you mean by "the rest of the Free Will Galaxy" and will be put off and unlikely to use a prayer they do not feel entirely comfortable saying with all the wording recommended. There are scourges of various kinds affecting the rest of the galaxy in parts, but in essence this is at present solely an exercise of the practitioners of the Lightworker Healing Protocol. We would love to see it embraced by the masses, but that has not happened yet. So you can be sure that the effects of these prayers are being gifted to others throughout the Milky Way Galaxy courtesy of the current practitioners. More is always better, but that will depend on human efforts to recruit more followers as practitioners of this fine healing tool and its comprehensive applicability to such things.
