Is she capable of keeping her daughter clear of spirit attacks by doing repeat Lightworker Healing Protocol sessions, or is she too close to the problem, perhaps for karmic reasons?

As we have spelled out in detail, she is not at fault or lacking. More to the contrary, is highly effective and a beautiful and loving advocate for her well-being and will continue to be so. It is just that every person is an individual and this is true of the daughter as well. She will push the limits, she will push and test the boundaries, she will exceed expectations but she will exceed your assumptions about her safety and vulnerability to the downside at times. This is just the nature of things and simply requires reasonable vigilance. If you have a regular routine to do session work on her at intervals, this would be ideal. In the meantime, daily prayers asking for the basics, for safety and removal of intrusive energies, will help to nip things in the bud and will work as good first aid to keep her safe. The full Protocol will not always be needed for simply removing new possessing spirits, but keep in mind with every human being there are many, many deep karmic issues always rumbling from the many parallel lifetimes that need to be addressed. So there is no time like the present to send as much healing outreach to her daughter as possible. It is a tremendous advantage for her to have the mother start now, especially when you consider that most people will not find their way to a practitioner of the Lightworker Healing Protocol until they are well advanced in years and have spent the majority of their life struggling and suffering from unresolved karmic burdens. Any and all healing the mother can do will be a tremendous blessing that will enhance all of her future.
