Energy can even by conveyed telepathically from one being to another - not quite as physical as the energy conveyed by sound waves - but it can be moved about between beings. Especially in a dream state. I have experienced it on a profound level on three occasions - and possibly even hundreds of times - when a loved one has communicated with me in the night.
I do not doubt that some women have the gift of healing - in fact I think it would be absurd to make the claim that they could not. It does NOT take formal Priesthood keys in order to heal those we love and care about. Especially when you consider the power of fasting and prayer.
I also want to say up front that the absolute cream of women I know, have gotten into this stuff and I neither support them in it, nor condemn them for it - but I do have a word of caution that echoes the official statement that just came out by the Church:
The Church has an official statement on energy healing!
“We urge Church members to be cautious about participating in any group that promises-in exchange for money-miraculous healings or that claims to have special methods for accessing healing power outside of properly ordained priesthood holders,” said church spokesman Eric Hawkins
I pretty much frown completely on anything that requires compensation for it's use. If it is a gift (that was given freely), then use and give that gift freely. Charging for anything along those lines, amounts to priestcraft in some form or another (picturing Christ turning the tables in the Temple right now).
As for women using their Priesthood, I encourage the exploration of it under the constant guidance of the Holy Ghost and while counseling with your husband (and other Priesthood leaders).
God WANTS us to develop our gifts FULLY - but there are many lying and deceiving spirits abroad in the land - and it is pretty easy to fall when covering "new ground". When jumping into anything new, I always move VERY slowly. It can take me years to move from comfortable ground into new territory - and thus the reason I consider myself the ultimate conservative. I am close to the scrips, the Constitution and also accepted spiritual leaders including Christ. The devil makes GREAT copies - and MANY have fallen for their snares. Knowing this - I move slowly. I would rather be dead than lead myself or my family astray.
